  • Amplifier With Improved Input Resistance and Controlled Common Mode
    Publication number: 20120019324
    Abstract: An amplifier includes a first pair of transistors (the first pair) that defines a first output, each transistor of the first pair having a gate coupled to a first input terminal; a second pair of transistors (the second pair) that defines a second output, each transistor of the second pair having a gate coupled to a second input terminal; a first capacitor coupled to the second output terminal and to the gate of a first transistor of the first pair; a second capacitor coupled to the second output terminal and to the gate of a second transistor of the first pair; a third capacitor coupled to the first output terminal and to the gate of a third transistor of the second pair; and a fourth capacitor coupled to the first output terminal and to the gate of a fourth transistor of the second pair.
    Type: Application
