A 5 GHz novel 0.18-/spl mu/m inductor-less CMOS sub-harmonic mixer

A novel CMOS low voltage inductor-less sub- harmonic mixer for 5 GHz Industrial Scientific Medical (ISM) band direct conversion receiver in an 0.18-µm SiGe Bi-CMOS process is presented. Simulated with 0.5% gm mismatch, 0.5% load mismatch and 2o LO I/Q phase error the mixer is able to achieve high IIP2 of 43.6 dBm, IIP3 of 0 dBm, and voltage conversion gain of 8.05 dB while consuming less than 2.6 mA from a single 1.8 V supply. Index Terms — CMOS, direct conversion receiver (DCR), Hiperlan2, IEEE 802.11a, ISM band, linearity, mixer, RF CMOS, sub-harmonic mixer, Zero-IF receiver.
