In this paper, analysis and design of a mm-wave distributed frequency doubler utilizing four push-push pairs in 65 nm CMOS is studied. In the proposed circuit, “gate transmission-line characteristic-impedance tapering technique” is introduced and analyzed to increase output power and efficiency of the frequency doubler. Using simulation, the impact of increasing the input voltage amplitude on improving the second harmonic power and efficiency for each frequency doubler unit cell is shown. In order to increasing the input voltage amplitude of the unit-cells, the characteristic impedance of the gate transmission-line is gradually increased. Utilizing this technique improves the output power by 6 dB. Holistic Electromagnetic simulation of the circuit, gives output power greater than -5 dBm in 60 GHz to 214 GHz band for an input power of 12 dBm and 24 mW power consumption.
