본 논문에서는 CMOS 저전압/저전력(LV/LP) 전압 제어 발진기(VCO)를 소개합니다. 여기에는 간단한 VI 변환기, 새로운 차동 지연 셀을 기반으로 하는 전류 제어 링 발진기, 차동 신호를 단일 종단 신호로 변환하는 소스 결합 차동 쌍이 포함되어 있습니다. VI 변환기는 소스 팔로워 유형으로 구현되어 낮은 전력 소비로 우수한 상호 컨덕턴스 선형성을 나타냅니다. 새로운 지연 셀은 로컬 포지티브 피드백을 사용하여 DC 이득을 높이고 낮은 공급 전압에서 안정적인 발진을 달성합니다. 시뮬레이션 및 측정 결과는 100V 전원 공급 장치를 사용하여 400MHz ~ 1MHz의 주파수 범위에서 입력(제어 전압)과 출력(주파수) 사이의 선형성을 보여주기 위해 제공됩니다. VCO는 작동 주파수 2MHz 및 2.25V 공급에서 400mW의 전력만 소비합니다.

Abstract: In this paper we introduce a CMOS low voltage/low power (LV/LP) voltage controlled oscillator (VCO). It includes a simple V-I converter, a current controlled ring oscillator based on new differential delay cells, and a source-coupled differential pair to convert differential signal to single-ended signal. The V-I converter is implemented as a source follower type, exhibiting excellent linearity of transconductance with low power consumption. The new delay cell employs local positive feedback to increase its DC gain, achieving stable oscillation at low supply voltage. The simulation and measurement results are given to show the linearity between the input (control voltage) and the output (frequency) in the frequency range of 100 MHz to 400 MHz with 1. 2 V power supply. The VCO only consumes power of 2.25 mW at operating frequency of 400 MHz and 1.2 V supply.
