A 60 Ghz Analog Phase Shifter in 65 Nm Bulk CMOS Process

A 60 GHz Analog Phase Shifter in 65nm bulk CMOS process has been explored for microwave frequency applications. It is an analog phase shifter with three transistors in the form of an active circulator and a LC network to attain the desired phase shift. This phase shifter is designed to work at a high frequency of 60 GHz to attain phase shift range of 140o. The proposed phase shifter works at supply voltage lower than 2.5 V. The phase shifter exhibits low insertion loss of 3.73 dB and low power consumption which is a challenging result for circuits working in microwave frequencies.
