CMOS MIXER FOR USE IN A DIRECT CONVERSION RECEIVER

摘要

A mixer for use in direct spread receiver is disclosed. This present invention of the embodiment in accordance with the mixer is a field effect transistor (FET: Field Effect Transistor) of M1 ~ M6 and the current source IBias and two load resistors (RLoad) and another FET M21 and two inductors L1, and a L2. FET M21 is the invention according to the current embodiment of the bleeding circuit (Current Bleeding Circuitry) The configuration and two inductors than the other components are the so-called Gilbert cell mixer (Gilbert Cell Mixer) and the configuration. ; Mixers, direct spread receiver, bleeding current circuit inductor
