TL;DR: In this paper, an offset signal is derived from a subtraction between the inputs of the PWM comparator, and the offset signals are injected into the comparator to cancel the output offset of the voltage regulator.
Abstract: In a low-gain current-mode voltage regulator having a PWM comparator in response to the varying output voltage and inductor current of the voltage regulator to produce a PWM signal to regulate the output voltage, an offset signal is derived from a subtraction between the inputs of the PWM comparator, and the offset signal is injected into the PWM comparator to cancel the output offset of the voltage regulator.

24 Mar 1995TL;DR: In this article, a threshold comparator with an input terminal and an output terminal, and a voltage divider connected between a first supply voltage reference and a second voltage reference, is proposed to detect a drop in a supply voltage.
Abstract: A circuit for generating a reference voltage and detecting a drop in a supply voltage, comprising at least one threshold comparator having an input terminal and an output terminal, and a voltage divider connected between a first supply voltage reference and a second voltage reference and connected to the input terminal of the comparator, further provides for the output terminal of said comparator to be connected to the input terminal through at least one feedback network comprising at least one current generator. The feedback network further comprises a buffer block having an input terminal connected to said comparator and a first output terminal connected to a switch which is connected between a circuit node of said voltage divider and the second voltage reference.
