연구실 소개
장우진 교수의 연구실은 고주파 및 마이크로파 회로 설계, 특히 알루미나간디아르메이트/ gallium nitride(AlGaN/GaN) 기반 고이동도 트랜지스터를 활용한 고성능 마이크로파 집적회로(MMIC) 기반 저노이즈 증폭기(LNA)의 설계 및 응용을 핵심으로 합니다. 또한, 생체입자 제어를 위한 마이크로플루이딕 기반 디젤렉트로포레시스 기술과 전자기기의 안정성 향상을 위한 미세구조 회로 기술에 대한 연구도 진행하고 있습니다. 실험적 검증과 모델링을 기반으로 한 신뢰성 분석 및 데이터 기반 신뢰성 추정 기법의 개발도 함께 수행하고 있습니다.
