Abstract :
A 0.13 mum CMOS 2.4 GHz balun-mixer is proposed, where a current-reused noise-canceling topology is adopted as the transconductance stage to reduce dc power consumption. After frequency conversion, noise-cancellation is achieved only when a specified condition is satisfied, but single-to-differential signal conversion is inherently obtained by the mixer operation. The fabricated chip shows a conversion gain of 13.5 dB, a single-side-band (SSB) noise figure of 8 dB, and an input-referred IP3 of - 6 dBm, while consuming only 3.5 mA from a 1.5 V supply voltage.
