Description

This report describes the design and analysis of a broadband inductor-less cascode-inverter based Cherry-Hooper amplifier. The methodology to maximize the bandwidth for a desired fan-out and gain is described. Simulation results of the extracted layout, in 28nm bulk CMOS, are presented. A bandwidth of 19.2GHz and a gain of 28.3dB were obtained, while consuming a power of 10.3mW, from a 1V supply. Additionally, the cascode bias can be used to tune the gain from 13.6dB to 29dB without significant impact on the bandwidth.
