Abstract

This paper demonstrates a CMOS downconversion mixer for 2.4GHz ISM band applications. The mixer, implemented in a 0.18um CMOS process, is based on the CMOS Gilbert Cell mixer, With a 2.5GHz local oscillator and a 2.45GHz RF input, the measurement results exhibit power conversion gam of -6dB, IIP3 of -6dBm, input $P_{-1dB}$ of -15 dBm, and power dissipation in mixer core of 2.7 mW with 0㏈m LO power and 1.8V supply voltage.
