BiCMOS 선형 OTA
A BiCMOS linear Operational Transconductance Amplifier
초록
A linear BiCMOS operational transconductance amplifier (OTA) is described. It consists of a CMOS linear transconductor and a bipolar translineear current gain cell followed by three CMOS current mirrors. The proposed circuit has comparable linearity and temperature stability but superior dc characteristics to its bipolar counterpart. A test circuit with a transconductance of 47.3
