Abstract: Integrated Circuits (ICs) comprising circuits configured to generate a power on reset (POR) pulse are disclosed. An IC comprises a power supply sense circuit configured to generate a sense signal in response to a transition of a power supply signal from a first level to a second level, and a pulse generation circuit coupled with the power supply sense circuit. The pulse generation circuit is configured to generate a power on reset (POR) pulse of a threshold duration based on the sense signal. The IC further includes a reset generation circuit coupled with the pulse generation circuit to receive the POR pulse. The reset generation circuit is configured to generate a reset pulse based on the POR signal and of at least one control signal, where the reset pulse is configured to be utilized to perform a reset of one or more elements of the integrated circuit.

Abstract: A system comprising an ambient energy source, a power supply, and a power storage device. The ambient energy source is coupled to a first terminal end of an inductor. The power supply is also coupled to the first terminal end of the inductor. The power storage device is coupled to a second terminal end of the inductor. The ambient energy source provides power through the inductor in a first direction to the power storage device. The power storage device provides power through the inductor to the power supply in a second direction opposite the first direction.

Abstract: Apparatus and method for controlling inductor current in a switch mode power supply. In one embodiment, a switch mode power supply includes an inductor, a high-side switch coupled to the inductor, a low-side switch coupled to the inductor, and a controller. The controller is coupled to at least one of the high-side switch and the low-side switch. The controller includes a first capacitor and a current source. The controller is configured to control timing of current switching to the inductor by enabling current flow through the at least one of the high-side switch and the low-side switch based on time to charge the first capacitor via the current source. The time is a function of voltage across the inductor.
