ABSTRACT:
An apparatus and method of reducing a flicker noise of a CMOS amplifier is provided. In the CMOS amplifier, a load circuit is connected to a signal input circuit which includes two pairs of MOSFETs which simultaneously receive differential signals. In this instance, a first MOSFET included in a switch-bias circuit is connected to one pair of MOSFETs which receive the differential signals and functions as a current source in the case of activation of a clock signal Ø1. A second MOSFET included in the switch-bias circuit is connected to another pair of MOSFETs which receive the differential signals and functions as a current source in the case of activation of a clock signal Ø2.
