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.

Abstract: Example current tracking circuits and systems as well as methods for tracking current are described herein. In one example, a current tracking circuit comprises a current mirror that receives a power supply input and a control signal as inputs, wherein the current mirror has a mirror ratio. The current tracking circuit also comprises a programmability sub-circuit coupled to the current mirror that trims a value of the mirror ratio. In another example, a method comprises performing current mirroring using a current mirror comprising a sense device, wherein a mirror ratio of the current mirror is based on a programmable sub-circuit. The method further comprises maintaining, by a voltage regulation loop, a collector potential of the sense device within a threshold difference level of a collector potential of a power device coupled to the sense device, wherein the sense device mirrors a current flowing in the power device.
