A RF Frequency Tripler with High Output Power in 180nm CMOS

Abstract

In this paper, a frequency tripler is designed to improve the output power and poor matching of traditional frequency tripler. Balun and passive components are designed for achieve good matching performance while suppressing fundamental wave and even harmonic wave. By using 180 nm CMOS technology, the 3-dB bandwidth spans 31.5 GHz ~ 36 GHz, the output power can be achieved to 7.9 dBm when injecting RF signal power of 0 dBm, the DC power consumption of the tripler is 36.9 mW with the power supply of 1.8 V.
