摘要：This paper describes design and simulation of a compact down-conversion oscillator-mixer for wireless communication applications. Simulation performed by Advanced Design System (ADS) in 0.18¦Ìm TSMC CMOS technology. Two different components, the mixer core, and the voltage-controlled oscillator (VCO) are assembled in a stacked structure. This permits the mixer current to be reused by the VCO cross-coupled pair to decrease the total current consumption of the VCO and mixer. The proposed oscillator -mixer operates over an radio frequency (RF) input range of 4.6 GHz to 5.6 GHz with a tunable local oscillator (LO) from 2.1 GHz to over 3.1 GHz. The intermediate frequency (IF) was kept constant at 2.5 GHz. The simulation results demonstrate 12.24 dB conversion gain at 4.6 GHz, 9.26 dB single sideband (SSB) noise figure, .115.6 dBc/Hz phase noise at 1 MHz offset from 2.5 GHz LO frequency and 3.49 mW total DC power consumption.
