In this paper, we briefly review the recent research on CMOS gigahertz-rate communication circuits. Then, we describe design innovations we have made to overcome limitations on communication speed. Using 0. 25-µm CMOS technology, we developed a 4.25-Gb/s Fibre Channel transceiver that features an asynchronous tree-type 1 : 8 demultiplexer and an 8-bit-to-10-bit frequency-conversion architecture. And using 0. 15-µm CMOS technology, we developed an 11. 8-GHz frequency divider that introduces the novel idea of a hysteresis-controlled latch (HC-latch). With these results, we discuss high-speed LSI design issues and future prospects.
