High-speed GaAs dynamic frequency divider using a double-loop structure and differential amplifiers

GaAs 2.0-8.0-GHz and 6.0-10.5-GHz dynamic frequency dividers have been developed. These dynamic dividers have a double-loop structure using a differential amplifier for high-speed and stable operation despite supply-voltage fluctuations. This structure operates from a single voltage supply. An advanced WSi self-aligned gate process technology (0.1- mu m long gate) was used to improve the high-frequency characteristics of the FET.<
