    Abstract:
    This paper considers CMOS digital communications receiver circuit design suitable for an all CMOS digital IC fabrication process. Use of a digital CMOS IC process results in significant differences in circuit design philosophy and topology. Digital ICs are designed to yield small, fast CMOS devices for digital logic gates and lack accurate or high speed resistances or capacitors, which has a significant impact on receiver design; active circuits replace functions ascribed to resistance and capacitance. The noise performance of CMOS amplifiers is different from bipolar or GaAs MESFET circuits, as shot noise is insignificant compared to channel thermal noise, and the optimal input stage topology is significantly different. It is found that, at operating speeds approaching the limits of the digital CMOS process, open loop designs have noise-power-gain-bandwidth tradeoff performance superior to feedback designs, and the lack of good resistors and capacitors means that feedback circuits are not generally used in the digital process CMOS receiver front-end. A circuit implementation and layout process and test results are given for a single-ended CMOS FDDI receiver as a design example
