Title : ‘A 2W CMOS Hybrid Switching Amplitude Modulator for EDGE Polar Transmitters’.

Abstract

An amplitude modulator for Class-E2 EDGE polar transmitters is fabricated in a 0.35um CMOS process. This hybrid switching modulator consists of a class-D amplifier with a 2MHz switching frequency and a wideband buffered analog amplifier having low output impedance of 200mΩ at high frequency. It can drive an RF power amplifier with an equivalent impedance of 4Ω up to maximum output power of 2.25W with a maximum efficiency of 88.3%. The chip area is 4.7mm2.

[ IEEE NMDC 2006 Best Paper Award on Nano CMOS Session ]

Yoo Seung-wan taking the Dr. degree courses of the department of Electrical Engineering Computer Science at KAIST was recently awarded the prize of Best Poster Paper Award at IEEE NMDC 2006 Conference.

‘IEEE NMDC 2006 Conference’ was held in Hyundai Hotel, Gyeongju, for October 10 ~ 25, 2006. During the period of the event, ‘Best Poster Paper Award’ meaning the best thesis of Nano CMOS Session, was the prize that chooses a prospective poster as to Nanotechnology materials and devices.
At that time, Mr. Yoo was honored by his thesis that Nanovolatile memory characteristics are presented with Ag nanocrystals(NCs) formed by a thermal decomposition process for a Flash memory application.

● The title of his thesis

“Nonvolatile Memory Characteristics of NMOSFET with Silver Nanocrystals Synthesized by Thermal Decomposition Process, S.-W. Ryu, C. B. Mo, S. H. Hong, and Y.-K. Choi, Korea Advanced Institute of Science and
technology

● The content of his thesis

Nonvolatile memory characteristics are presented with Ag nanocrystals (NCs) formed by a thermal decomposition process for a Flash memory application. A size of NC and a space of NC-to-NC were precisely controlled by a size-selective precipitation technique and the length of self-assembled monolayer surrounding NCs, respectively. The size and density of Ag NCs synthesized by the thermal decomposition were typically 3-5 nm and 2.7×1012 cm-2. Nonvolatile memory operations with relatively high speed and superior endurance characteristics were reported from NMOSFETs embedding metal NCs, which were fabricated by the gate last process.

youngsuk son and yongjoon jun (advisor: Professor Cho, Gyu-Hyeong) a Ph.D. student of Department of Electrical Engineering of KAIST, won the MOCIE(Ministry of Commerce, Industry and Energy) minister prize, at 7th semiconductor design contest hold from KIPO(Korean Intellectual Property Office )

Abstract:
Offering wide viewing angle, fast response, low power consumption, and thinness, AMOLED displays hold promise as next generation flat panel displays. Compared to LCDs, PDPs, and CRTs, however, the quality of AMOLED displays from a display uniformity point of view is not satisfactory.
In this design contest, the novel data driving scheme and driving circuits are proposed and verified with electrical experiments for enhancing display quality and lifetime of AMOLEDs. The concept of the novel driving scheme is named Transient Cancellation Feedback (TCF) and published in SID2006.
The proposed TCF driving scheme provides unique Active-Matrix architectures and overcomes the limitation of traditional approaches.
The data driving speed in conventional current-mode driving methods is dramatically enhanced by the proposed TCF driving and the achieved performance of the driving circuits is applicable to the commercial products.
The progress of the display quality and lifetime of AMOLEDs are expected with the application of TCF driving to AMOLEDs.

The Korean Institute of Communication and Sciences (KICS) held the award ceremony of 2006 summer conference of KICS at Inha university on November 18, 2006.

Hyoungmoon Kwon (advisor: Professor Iickho Song), a Ph.D. student of Department of Electrical Engineering of KAIST, had the honor of receiving the best paper award.

Nearly 500 papers were in the pool for the contest,and only 2 papers were awarded after rigorous examination. (Title of paper: Constant False Alarm Rate Schemes with Receive Diversity for Code Acquisition in Homogeneous Fading Circumstances)

Professor Iickho Song received the Haedong Information and Communications Academic Award from KICS at the Annual General Meeting of the KICS held at Inha University on November 18, 2006.

During the recent 5 years, Professor Song has contributed in the field of information and communications by a number of excellent papers including ‘A Novel Detection Criterion for Weak in M-ary Signals and Its Application to Ultra Wideband Multiple Access Systems’.

Sungwook Choi and Heeseok Han, both in doctorate course at KAIST Department of Electrical Engineering, won best prize and gold prize respectively at the 1st Fairchild Korea Graduate Student Paper Contest.
The title of Choi’s paper is ‘Cost Effective Multi-Level Single Sustaining Driver for Plasma Display Panel with Dual Energy Recovery Path’.

And the title of Han’s paper is ‘Digital Control IC for Electronic Ballast using Mixed Mode Excitation’.
Choi’s paper proposes a new driver that can avoid the problems of IGBT, a power switch used at PDP driving circuit, gaining attention as next-generation display, for cost-reduction. Choi showed his feeling of pleasure by saying, “I’m very pleased that my paper can contribute to PDP popularization and development of power switch for PDP through cost-reduction. I’d like to acknowledge Professor Kunwoo Moon, who has instructed me with persistence and interest at all times.”

Intel, Korea, announced the awardees of the Intel Student Thesis Contest 2006 at the Intel Developer Forum (IDF) conference. The purpose of this event is to promote the outstanding research performance in technology development via the cooperation between the domestic research institutes and academic field.

For this second contest following the previous year’s one, 55 thesis on core future technology such as digital home environment and next generation wireless communication were submitted. Overall qualities of the papers were said to be increased, which made the event more competitive.

Among the papers submitted by the graduate students of 47 ITRC laboratories from 27 schools, eight papers were selected as one gold, 2 silvers, and 5 bronzes. Each awardee is given the prize of 10 to 30 millions won or gift. The decision board consisted of 7 experts from academic and industrial world; which included Ph.D Song, Jung-Hee (IT strategy advisor, Ministry of Information and Communication) and Professor Kang, Chul-Hee from EECS, Korea University (also the president of ITRC Commitee). The selection of the papers was based on their research performance, uniqueness, and creativities.

The grand prize was given to Jung, Jin-Gon, Ph.D student from CHiPs (Center for High-Performance Integrated Systems) at KAIST. He suggested a key approach for the next mobile technology communication; the title of the paper was, “Regularized channel diagonalization for multi-user MIMO downlink using a modified MMSE criterion”.
The decision board praised the suggested new linear processing algorithm which has better performance to the technology based on ZF and MMSE in MIMO (Multi Input Multi Output) environment. MIMO technology is designed to reduce errors and increase the transmission capacity with multiple antennae.

“This gold prize winning paper suggested the most advanced technology to increase the spectral efficiency in the MIMO field, which is one of the core tasks in the development of WIMAX. It proves its significance. Other than that, all the prize winning papers showed the creative research performances for the industrial development.”, Ph.D Song, Jung-Hee mentioned.
