基于吉尔伯特型的CMOS射频混频器的设计
Design of CMOS RF Mixer Based on Gilbert Cell
摘要
Abstract
A novel double channel quadrature mixer is 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 SSB noise factors were 7.47 dB/Hz@ 1 MHz,9.35 dB/Hz@ 1 MHz and 16.39 dB/Hz@10 kHz when the input power was equal to 3 dBm with VDD=1.8 V.In addition,the conversion gain decreased to 8.46 dB to increase linearity,and the 3th point of intermodulation was 8.42 dBm.关键词
