Abstract :
A divide-by 256/258 dual-modulus prescaler IC has been successfully fabricated using GaAs JFETs with a gate length of 0.5 mu m. The prescaler IC consists of nine flip-flops, two NOR gates, three OR gates, and three I/O buffers. These circuits were constructed using a three-level SCFL (source coupled FET logic) gate. A maximum operating frequency of 12 GHz was obtained with a power consumption of 2.2 W, including power for buffer circuits, which is the highest frequency for a dual-modulus prescaler IC to date.<>
