Abstract :
We present a static frequency divider with a divide ratio of 16. The circuit is realized in current-mode logic (CML) and operates up to a maximum frequency of 62 GHz. The first master-slave flip-flop uses shunt peaking and consumes only 4 mW from a 2 V supply. The total supply current including all four divider stages and buffers is 12 mA. The circuit is manufactured in a 200-GHz fT SiGe bipolar process.
