Abstract
The letter describes the high-speed performance of a 4:1 time-division MSI multiplexer and demultiplexer, which are fabricated using advanced super self-aligned process technology (SST). The maximum operation speed of the multiplexer is 5.02 GHz under 576 mW power dissipation. The system, which is composed of a multiplexer and a demultiplexer, operates at up to 4.80 GHz. The demultiplexer has a power dissipation of 1148 mW. Interchannel interference is also examined.
