2011 Sixth IEEE International Symposium on Electronic Design, Test and Application，Ki-Jin Ki&K. H. Ahn；This paper presents a design of 60 GHz active phase

shifter for next generation mm-Wave WPAN using 90 nm

TSMC CMOS technology. The vector modulator based phase

shifter is chosen as a prototype because it provides accurate

resolution over 360 degree. The phase shifter is controlled by 5

bit digitally controlled by binary current weighted DAC. The

miniaturized Marchand balun and 2 stage poly phase filter are

used to generate differential I/Q signal from single signal. The

three CS amplifiers are implemented for providing gain to the

proposed circuit. The measured phase resolution of the circuit is

11.250 with maximum 30 phase error. The peak gain from the Sparameter

measurement is 9 dB while drawing 50 mA from a 1.2

V supply.
