GaAs multiplexer chip for ATM switching

Abstract

This paper describes the design of a GaAs multiplexer chip which can be used for the implementation of an ATM switch fabric. In order to achieve low power, a self-timed FIFO with automatic power off was designed. For high speed and low power a static flip-flop with push-pull output stage was also designed. The chip works at 1.15 GHz, corresponding to a throughput of 10 Gb/s. This is achieved at a power consumption of 1.2 W.
