Abstract: A peak efficiency detection system may include a switched power supply (SPS) module providing an output supply signal. The SPS module may have an internal node, and a plurality of SPS circuits configured to generate the output supply signal on the internal node. A dead type module may generate control signals. A central node external to the SPS module may deliver the output supply signal to a load module. A power stage size control module may generate control signals for controlling the SPS module. A peak-efficiency detection (PED) module may receive the output supply signal from the central node, the control signals from the SPS module, and the control signals from the power stage size control module. The PED module may generate a signal representative of an efficiency of the SPS module.

Abstract: A valley inductance current polarity change in a pulse width modulated circuit charged with an inductive charge is detected by comparing respective times that a first output of the circuit charged with an inductive charge and a second output of a pulse width modulated reference circuit with no inductive charge reach an output level. Responsive thereto, control over operation of the pulse width modulated circuit charged with an inductive charge is made with respect to switching to a pulse skipping mode of operation or keeping the pulse width modulation mode of operation.

Abstract: A circuit includes a current source, a differential pair of transistors coupled to the current source, an active load, and a current injection circuit. The differential pair of transistors has a first offset voltage and an input transconductance. The current injection circuit is configured to supply a first current and a second current to produce a second offset voltage across the differential pair of transistors opposite the first offset voltage. The first current and the second current has a same thermal dependence as the input transconductance of the differential pair of transistors.
