Abstract
In some examples, a device includes an amplifier circuit configured to receive a reference voltage signal at a first input, receive a feedback signal at a second input, and generate an output signal based on the reference voltage signal and the feedback signal. In some examples, the device also includes a feedback circuit including a soft-shaper circuit that is electrically connected to the second input of the amplifier circuit. In some examples, the feedback circuit is configured to sense a voltage step in the reference voltage signal, generate a voltage step across the soft-shaper circuit approximately equal to the voltage step in the reference voltage signal in response to sensing the voltage step in the reference voltage signal, and ramp a voltage level across the soft-shaper circuit to zero after generating the voltage step across the soft-shaper circuit.
