A Novel Low-Voltage CMOS Mixer with Differential Floating-Gate Input

Article Preview

Abstract:

In order to adapt to low-voltage operating of the Gilbert CMOS integrated mixer, a novel mixer is researched which with floating gate amplify transistor and a few stack from the power supply to the ground. The mixer had some advantages that are avoided the input DC voltage imbalance and suppressed 1/ f noise. The mixing feasibility is confirmed by time domain simulation, and the mixing output signal quality is analyzed by spectrum simulation. The results show that the mixer output main spectrum is the difference for various frequency input signal. The main-spectrum is more than 6dB with three order inter-modulation interference amplitude.
