Abstract :
A low-voltage, low-power mixer operating at a supply voltage of 0.9 V while consuming 4.7 mW is presented. The circuit achieves the multiplication using current mode processing. Moreover, non-conventional differential pairs that do not require current tail generators are utilized. The circuit has been fabricated in a standard double-poly, triple-metal 0.35 μm CMOS process having a threshold voltage of 0.6 V. Measurement results for 900 MHz and 800 MHz input signals indicate that the circuit has an IIP3 of 3.5 dBm, a 1 dB compression point of -8 dBm and a noise figure of 13.5 dB
