본 논문에서는 레일-투-레일 스윙을 갖는 펄스 형태의 전압 신호를 이용하여 테일 트랜지스터를 구동하는 펄스-테일-피드백 VCO를 제안한다. 제안된 PTFB(펄스-테일-피드백) VCO는 테일 트랜지스터의 전류 전도 기간을 줄이고 180극관 영역의 테일 트랜지스터를 작동하여 능동 소자의 깜박임 및 열 잡음을 줄이는 데 의존합니다. 제안된 기술의 유효성을 검증하기 위해 제안된 PTFB-VCO의 위상 잡음 메커니즘에 대한 수학적 분석 및 회로 레벨 시뮬레이션도 이 문서에 제시되어 있습니다. 제안된 PTFB 기술을 사용한 프로토타입 LC-VCO는 표준 1.35nm CMOS에서 제작되었습니다. 실험실 측정에 따르면 1.2GHz에서 4.6V 전원으로 700mW의 전력 소비가 발생합니다. 제안된 PTFB-VCO는 195Hz의 플리커 코너를 달성하므로 VCO는 1kHz~10MHz의 넓은 오프셋 주파수 범위 내에서 -XNUMXdB의 상당히 일정한 FoM(성능 지수)을 유지할 수 있습니다.

Abstract: This paper proposes a pulse-tail-feedback VCO, in which the tail transistor is driven using pulse-shaped voltage signals with rail-to-rail swing. The proposed pulse-tail-feedback (PTFB) VCO relies on reducing the current conduction period of the tail transistor and operating the tail transistors in triode region for reducing the flicker and thermal noise from the active elements. Mathematical analysis and circuit level simulations of the phase noise mechanism in the proposed PTFB-VCO is also presented in this paper for validating the effectiveness of the proposed technique. A prototype LC-VCO with the proposed PTFB technique is fabricated in a standard 180nm CMOS. Laboratory measurement shows a power consumption of 1.35mW from a 1.2V supply at 4.6GHz. The proposed PTFB-VCO achieves a flicker corner of 700Hz, which enables the VCO to maintain a fairly constant figure-of-merit (FoM) of -195dB within a wide offset frequency range of 1kHz-10MHz.
