아날로그 및 무선 통신 신호처리 연구실의 연구 결과가 회로 및 시스템 분야 권위지인 IEEE Transactions on Instrumentation and Measurement (IF = 5.6, 상위 11.2%)에 게재되었다. 논문 제목은 ‘Wide Range and Tunable Pulse Generator in CMOS 45-nm Technology for Pulse Radar Array’로, 본 연구를 통해 MIMO (Multi-input Multi-output) Pulse Radar Array에 적용한 폭 및 간격 조절 가능한 다중 펄스를 제안한다. 제안된 펄스 생성기는 DLL (Delay Locked-Loop)을 통해 정확한 간격 폭을 가진 다위상의 기준 펄스 생성, 이후 NOR Gate 기반 펄스 생성을 통해, 기존 기술 대비 향상된 INL (Integrated Non-Linearity) 및 DNL(Differential Non-Linearity) 성능을 달성하였다.

아날로그 및 무선 통신 신호처리 연구실은 아날로그 회로 기술 기반 다양한 무선 송수신 회로 및 bio-medical 회로 연구를 진행 중이며, CMOS 기반 RF Wireless Transceiver 연구를 선도하고 있다. 본 논문은 한국전자통신연구원(ETRI)와 공동 연구를 통한 산출물이며, 정보통신기획평가원(IITP), 한국연구재단(NRF)의 지원을 받은 연구 산출물이다. Muhammad Fakhri Mauludin (한밭대학교 박사 과정)이 제1저자, 김주성 교수가 교신저자, 공동 연구를 수행한 ETRI의 지능형반도체연구본부 (구본태 본부장, 강동우 책임, 최장홍 책임, 백영석 책임)가 공동 연구자로 참여하였다
