Abstract :
This paper presents an up-conversion mixer for 2.4GHz wireless sensor networks (WSN) in 0.18μm RF CMOS technology. It was based on a double-balanced Gilbert cell type. Operational amplifiers (OP) were used in this design to improve the conversion gain. The performance was verified via simulation using Cadence SpectreRF. The post simulation results indicated that under 1.8V power supply the conversion gain was 16.2dB and the input referred 1dB compression point was -20.7dBm and it consumed 5mA current.
