0.18 /spl mu/m CMOS sub-harmonic mixer for 2.4 GHz IEEE802.15.4 transceiver

Abstract

This work describes a sub-harmonic mixer designed in a 0.18 /spl mu/m CMOS process and intended for use in a low-power IEEE 802.15.4-compliant 2.4 GHz transceiver. The device addresses the following issues of the direct conversion architecture: flicker-noise, LO leakage and oscillator pulling.
