Abstract :
A 60-GHz phase-locked loop (PLL) with inductor-less prescaler is fabricated in a 90-nm CMOS process. The inductor-less prescaler has a smaller chip area than previously reported ones. The PLL operates from 61 to 63 GHz and consumes 78 mW from a 1.2 V supply. The phase noise at 100 kHz and 1 MHz offset from carrier are -72 and -80 dBc/Hz, respectively. The prescaler occupies 80 x 40 mum2. The active area of the PLL is 0.6 x 0.6 mm2.
