Abstract :
A completely integrated 19 GHz static 2:1 frequency divider in 120 nm CMOS is presented. The divider operates up to 19 GHz and features an enhanced input sensitivity of 0 dBm over a broad input band of 15 GHz. The circuit draws 44 mA from a single 1.5 V supply. To drive 50 /spl Omega/ loads up to 9.5 GHz, an output buffer is also included in the divider circuit.
