Differential difference amplifier circuit having variable transconductance
The differential difference amplifier circuit includes a differential input stage circuit, a loading stage circuit coupled to the differential input stage circuit, and an output stage circuit coupled to the loading stage circuit. The output stage circuit is configured to generate an output signal. The differential input stage circuit includes a first differential pair having a first transconductance and a second differential pair having a second transconductance. The first differential pair is biased by a first current source and receives a first input signal and the output signal. The second differential pair is biased by a second current source and receives a second input signal and the output signal. At least one of the first transconductance and the second transconductance is adjusted according to the image data.
