Abstract
A new CMOS mixer topology can operate at low supply voltages by using switches connected only to the supplies. Mixing is achieved exploiting two cross-coupled transconductors, which are alternatingly activated by the switches. A down conversion mixer prototype with 12 dB conversion gain was designed and realized in standard 0.18 μm CMOS. It achieves satisfactory mixer performance up to 4 GHz, at a supply voltage of 1 Volt. Moreover, the mixer topology features a fundamental high frequency noise figure benefit.
