Abstract: A circuit and associated method for determining the offset bias of a comparator by first shorting together the inputs of the comparator to apply the same voltage signal at each of the inputs of the comparator. The voltage signal at one of the inputs is then offset a select amount by applying varying selected resistances from a variable resistor to the comparator. The variable resistor is controlled by a programmable controller that is responsive to an input clock signal. At each selected amount of offset applied to the input, the output is monitored to determine if the output of the comparator has flipped, or changed state. When the output flips, the corresponding resistance setting is used to compensate for the corresponding offset bias of the comparator.

Abstract: The present invention regulates a power signal provided by a power source and includes two operational modes: a first mode capable of consuming low amounts of static power; and a second mode capable of smoothing voltage spikes appearing at high frequencies. The present invention further includes a generator, amplifier, and a regulator for controlling the power signal; a device for determining whether the present invention should be in the first or second operational mode; and a device for shifting between the first and second operational modes.
