This book presents innovative strategies to implement ultra-low voltage (ULV) and low power active circuits used in low energy RF receivers. The authors demonstrate that the use of single-stage amplifiers with the input negative transconductance compensation is a key strategy to allow the operation at low voltage levels with reduced power dissipation. Also, some design methodologies, based on the CMOS transistor operation point, are analyzed and a powerful design methodology is described for this kind of circuit. Readers will be enabled to implement the techniques described to design communication circuits with low power dissipation, useful in a variety of applications, including IoT/IoE devices.

Lucas Compassi-Severo received the B.Sc. and M.Sc. degrees in electrical engineering from the Federal University of Pampa, Brazil, in 2011 and 2012, respectively, and the Ph.D. degree in electrical engineering from the Polytechnic School, University of São Paulo, in 2019.
