Abstract
A novel double channel quadrature mixer was proposed in the paper. In this mixer, polycrystal resistance, source injection current of switch transistor, series inductor of common source node, degeneration impedance in driving stage were adopted. The circuit was designed and simulated by Candence. The results indicated that the phase noise were 7.47 dB/Hz@1MHz, 9.35 dB/Hz@100KHz and 16.39 dB/Hz@10KHz when the input power was equal to 3 dBm with VDD=1.8V. In addition, the conversion gain decreased to 8.46 dB to increase linearity, and the 3th point of intermodulation was 8.42 dBm.
