The Design of a 140 GHz 28 nm CMOS Vector-Sum Phase Shifter Based on Gilbert Cell and Current-Steering Amplifiers
This paper presents the design of a 140 GHz vector-sum phase shifter in a 28 nm CMOS process. Two variable-gain amplifiers—Gilbert cell and current-steering amplifiers—are investigated and compared. The Gilbert cell-based phase shifter controls the tail current source in a common-source amplifier. H...
