Abstract

In this work, a 54 GHz divide-by-3 injection-locked frequency divider(ILFD) based on ring oscillator has been developed in a 0.13-${\mu}M$ Si RFCMOS technology for phase-locked loop(PLL) application. The free-running frequency is 18.92~19.31 GHz with tuning range of 0~1.8 V, consuming 70 mW with a 1.8 V supply voltage. At 0 dBm input power, the locking range is 1.02 GHz(54.82~55.84 GHz) and, with varactor tuning of 0~1.8 V, the total operating range is 2.4 GHz(54.82~57.17 GHz). The fabricated circuit size is 0.42 mm${\times}$0.6 mm including probing pads and 0.099 mm${\times}$0.056 mm for core area.

본 논문에서는 54 GHz 대역의 위상 고정 루프에서 사용되기 위한 Ring 발진기를 이용한 3 분주 주입 동기 주파수 분주기(Injection-Locked Frequency Divider: ILFD)를 0.13-${\mu}M$ Si RFCMOS 공정을 이용하여 설계, 제작한 결과를 보인다. 1.8 V의 공급 전압에 대해서 buffer단을 포함하여 70 mW의 전력을 소비하며, 입력 신호가 없을 때 0~1.8 V의 varactor 조정 전압 범위에 대하여 18.92~19.31 GHz에서 자유 발진(free-running oscillation)을 하였다. 0 dBm의 입력 전력에 대해서 1.02 GHz(54.82~55.84 GHz)의 동기 범위(locking range)를 가지며 varactor 조정(0~1.8 V)을 포함한 동작 범위(operating range)는 약 2.4 GHz(54.82~57.17 GHz)를 보였다. 제작된 회로의 크기는 측정 pad를 포함하여 0.42 mm${\times}$0.6 mm이며, pad를 제외한 실제 동작 영역의 크기는 0.099 mm${\times}$0.056 mm이다.
