Abstract
The present invention provides a frequency-compensated transconductance amplifier, includes an input stage consisting of NMOS transistors M1 and M2, a first-stage active load consisting of PMOS transistors M3 and M4, a first-stage tail current source consisting of a constant current source Iss, a second-stage input transistor consisting of a PMOS transistor M5, a second-stage constant current source consisting of an NMOS transistor M6, a load capacitor consisting of a capacitor CL, and a frequency compensation network formed by sequentially connecting a gain stage GAIN, a compensating resistor Rc and a compensating capacitor Cc in series.
