The authors describe the ultrahigh-speed performance of static flip-flop divide-by-two circuits implemented in both buffered FET logic (BFL) and capacitively enhanced logic (CEL) families utilizing 0.2-μm gate-length Al.48In.52As-Ga.4 7In.53As high-electron-mobility transistors (HEMT) fabricated on InP substrates. The dividers were tested on-wafer using a probe station at 300°K temperature. The highest operating frequency at 25.4 GHz was achieved with a CEL divider. At this frequency the divider dissipated 63.8 mW. A BFL divider operated at 25.2 GHz with 450 mW power dissipation.
