Abstract
- A frequency divider with super-dynamic D-type flip–flop is demonstrated in 2 µm GaInP/GaAs HBT ( fT = 40 GHz) technology. By biasing the HBT devices around the peak transit-time frequency ( fT), the operating frequency of a D-FF with ECNFP (emitter-coupled negative feedback pairs) can be improved. At a supply voltage of 5 V, a divide-by-two function of 9.5 GHz is achieved. [ABSTRACT FROM AUTHOR]
