Abstract: A trimming resource includes an adjustable driver resource, a differential voltage generator, and a trim current generator. The adjustable driver resource produces an output signal. The differential voltage generator receives the output signal from the adjustable driver resource and produces a differential drive signal. The trim current generator derives a trim signal from the differential drive signal received from the differential voltage generator. According to one configuration, the trim current generator outputs the trim signal to an electronic component, correcting an operational parameter of the electronic component.

Abstract: Compensation circuits, compensated voltage regulators, and methods are provided for stabilizing voltage regulators, or other circuits that use operational amplifiers, over a wide range of output current. The described techniques provide a zero whose frequency varies linearly with an output current, and which can be used to track and compensate for a pole whose frequency similarly varies with the output current. The variable-frequency zero is created using a compensation capacitor placed in series with a variable resistance, wherein the resistance is configured to vary linearly with the output current. A pole-tracking zero generated in this way may be used to overcome difficulties encountered when the gain of a system includes a pole whose frequency varies with output current, and serves to improve the phase margin of amplifier circuitry, including that used within voltage regulators, and/or serves to ensure stability over a wide range of output current.
