Abstract:
1. An amplifier device, comprising: a differential transistor pair for receiving a differential input signal, wherein a first transistor of the differential pair provides a non-inverting input of the amplifier device and a second transistor of the differential pair provides an inverting input of the amplifier device; an amplification stage operatively coupled to the differential transistor pair, the amplification stage including a third transistor serially connected with the first transistor of the differential pair, and a fourth transistor serially connected with the second transistor of the differential pair, wherein the third transistor is configured to receive a bias voltage on its input, and acts as a current source; and a resistive-capacitive compensation network operatively coupled across the third transistor and to an input of the fourth transistor, wherein the compensation network includes a resistor serially connected to a capacitor.
