Abstract
An injection-locked ring oscillator fabricated in a 0.18-/spl mu/m CMOS process is presented for high-speed applications. By tuning the free-running frequency, the proposed circuit provides 2:1 and 4:1 frequency division over a wide input frequency range. The measured input frequency range covers 16.7-25.2 GHz and 41.2-46.9 GHz for 2:1 and 4:1 frequency division, respectively. The divider core operates at a 1.8-V supply voltage with a power consumption between 21.0 and 23.8mW for the entire frequency tuning range.Keywords
