Abstract :
An alternative low-voltage latch topology based on switched emitter followers is proposed, and its characteristics are compared to a traditional current-mode latch. A static 1:8 frequency divider based on this latch is implemented in a SiGe BiCMOS technology with fT=120 GHz. The divider operates at a maximum frequency of 42 GHz and consumes 160 mW from a 2.1 V power supply.
