Optimization methodology based on IC parameter for the design of radio-frequency circuits in CMOS technology

Abstract

This chapter presents a computational methodology for the design optimization of ultra-low-power CMOS radio-frequency front-end blocks. The methodology allows us to explore MOS transistors in all regions of inversion. The power level is set as aninput parameter before we begin the computational process involving other aspects of the design performance. The approach consists of trade-offs between power consumptionand other radio-frequency performance parameters. This can help designers to seek quickly and accurately the initial sizing of the radio-frequency building blocks whilemaintaining low levels of power consumption. A design example shows that the best trade-offs between the most important low-power radio-frequency performances occur in the moderate inversion region.
