Abstract

This paper presents a new low voltage CMOS micromixer for 2.45GHz applications, which operates at 1V supply voltage. The new low voltage CMOS micromixer topology modified from basic BJT micromixer uses coupling capacitors to feed the RF signal so as to bias the two transistors in RF stage separately with lower voltage. The charge injection method is also adopted to improve the conversion gain and linearity under low voltage operation. With a power consumption of 1.72 mW the measurement shows voltage gain of 8.28 dB, input 1dB compression point of -5.63 dBm and input third-order intercept point of 4.21 dBm.
