Abstract: Aspects of the disclosure provide for a circuit. In some examples, the circuit includes a first comparator, a second comparator, and a logic circuit. The first comparator includes a first input terminal coupled to a first node, a second input terminal coupled to a second node, and an output terminal. The second comparator includes a first input terminal coupled to the first node, a second input terminal coupled to a third node, and an output terminal. The logic circuit includes a first input terminal coupled to the output terminal of the first comparator, a second input terminal coupled to the output terminal of the second comparator, and an output terminal. The logic circuit is configured to determine a change in current over time based on analyzing an output signal of the first comparator and an output signal of the second comparator over a plurality of sequential cycles of operation.

Abstract: A circuit includes a first transistor and a second transistor coupled to the first transistor at a switch node and to a ground node. An estimator circuit receives a first signal to control an on and off state of the first transistor. The estimator circuit generates a second signal to control the on and off state of the second transistor. The second signal has a pulse width based on a pulse width of the first signal. A clocked comparator includes a clock input, a first input, and a second input. The first input receives a voltage indicative of a voltage of the switch node. The second input is coupled to a ground node. The clock input receives a third signal indicative of the second signal. The clocked comparator generates a comparator output signal. The estimator circuit adjusts the pulse width of the second signal based on the comparator output signal.
