Abstract:
An amplifier circuit, comprising:a differential transistor pair that provides first and second output signals;a first load having a first terminal coupled for receiving the first output signal;a second load having a first terminal coupled for receiving the second output signal;a feedback transistor having a control terminal coupled to second terminals of the first and second loads and a first conduction terminal coupled to a first power conductor;a signal-inverting transistor having a control terminal coupled to a second conduction terminal of the feedback transistor, a first conduction terminal coupled to a second power conductor, and a second conduction terminal coupled to commonly coupled terminals of the differential transistor pair;a first current source having a first terminal coupled to the second conduction terminal of the feedback transistor and a second terminal coupled to the second power conductor; anda second current source having a first terminal coupled to the first conduction terminal of the signal-inverting transistor and a second terminal coupled to the second power conductor.
