چکیده
This paper presents a current re-use quadrature front end receiver architecture for ISM Band. The proposed architecture is a stacked QLMV cell which consists of a low-noise amplifier (LNA), mixer and voltage-controlled oscillator (VCO), which feeds into the intermediate frequency (IF) load. The LNA is a common source amplifier with Ls source degeneration, a double-balanced Gilbert cell mixer and a parallel VCO. Two IF load architectures are presented in this paper, IF_1 and IF_2. IF_1 is a basic transimpedance amplifier and IF_2 is a a complex transimpedance amplifier with output buffering. This design was implemented in 0.13μm CMOS technology and the results obtained show a S11 of -18.51 dB, P-1dB of -41.5 dBm, VCO phase noise of -116 dBc/Hz @ 1MHz and a noise figure of 12 dB with the differential amplifier based TIA (IF_2) and 9.8 dB with the output buffered differential amplifier IF load (IF_1) and has an overall power dissipation of 2.16mW.
