A 60GHz Active Phase Shifter Integrated with LNA
This chapter presents a 4-bit active RF phase shifter that is based on programmable weighted combinations of I/Q paths with digitally controlled variable gain amplifiers (VGAs). With the use of the 4-bit active RF phase shifter, this chapter describes the design and measurement results of a 60GHz two-path receiver in which each path consists of a low noise amplifier (LNA), a phase shifter and part of a combiner, in a 65nm CMOS technology.
