FMCW 레이더 적용을 위한 넓은 Locking Range와 높은 Sensitivity를 갖는 링 발진기 기반의 Injection-Locked 주파수 분주기

다국어 초록 (Multilingual Abstract)

This paper introduces a dual injection-locked frequency divider (ILFD) based on a ring oscillator, designed to achieve a broad locking range by adjusting the self-oscillation frequency through load resistor regulation. Unlike traditional ILFD designs that rely on single injection, our proposed ILFD achieves a wider locking range by incorporating dual injection. This method boosts the injected current and increases the ratio of injected to undisturbed current. <BR/>The ILFD structure developed in this work operates within a locking range of 6.7 GHz to 43.1 GHz, with power consumption measured at 4.374 mW at the target input frequency of 16 GHz. The design was implemented using the 40 nm CMOS process, and the chip area is 132.52 μm × 114.78 μm.
