This paper discusses the design, analysis and performance of a 2.4GHz fully integrated low-power current-reused receiver front-end implemented in 0.18@mm CMOS technology. The front-end is composed of a single-to-differential low-noise amplifier (LNA), using high-Q differential transformers and inductors and a coupled switching mixer stage. The mixer transconductor and LNA share the same DC current. Measurements of performance show a conversion gain of 28.5dB, noise figure of 6.6dB, 1dB compression point of -32.8dBm and IIP3 of -23.3dBm at a 250kHz intermediate frequency, while dissipating 1.45mA from a 1.2V supply.
