• 論文の詳細を見る

• This paper presents a frequency-controllable image rejection mixer in heterodyne architecture for 2GHz applications based on TSMC 0.18μm CMOS technology. The designed mixer uses a notch filter to suppress the image signal and allows precise tuning the image frequencies. An image rejection of 20-70dB is obtained in a 200MHz of bandwidth. The simulation results show single-side band (SSB) NF is improved 3.7dB, the voltage conversion gain of 14.7dB, improved by more than 4dB. The circuit operates at the supply voltage of 1.8V, and dissipates 11.34mW.
