FREQUENCY COMPENSATION IN AMPLIFIERS WITH LOCAL-FEEDBACK BUFFER STAGES

Examples of circuits, amplifiers, and stages thereof are provided that improve amplifier stability margins while maintaining signal fidelity. Example structures include pre-driver circuitry; a compensation node exhibiting high impedance during operation; a feedforward driver coupled to the pre-driver circuitry; and first and second signal mirrors; and first and second output drivers, each having a control terminal. Example structures further include feedforward circuitry in which a first node thereof is coupled to the output of the feedforward driver, a second node thereof is coupled to the control terminal of the first output driver, and a third node thereof is coupled to the control terminal of the second output driver; and compensation circuitry in which a first node thereof is coupled to the compensation node, a second node thereof is coupled to a first internal node of the first signal mirror, and a third node thereof is coupled to a second internal node of the second signal mirror.
