- Abstract
A complementary passive mixer with feedback followed gate bias generation scheme is proposed. The gate voltage of the switches follows the common‐mode voltage (VCM) of the signal paths, so that the proposed mixer achieves constant switching gate‐to‐source bias voltage and coherent performances while VCM changes over a certain range. Furthermore, a dc offset cancelation method based on the bias generation circuit is proposed. The dc component of the intermediate frequency is feedbacked to the bias generation input to form a cancelation path. A behavioural model is deduced to prove the effect of the offset cancelation and second intercept point (IIP2) improvement. The proposed mixer is implemented in a 0.13 μm CMOS process, and measurement results show that robust performance with the VCM range of 0.5–0.7 V and 16 dB IIP2 improvement are obtained.
