How does a comparator circuit work
WebApr 12, 2024 · An example feedback loop circuit for a switching regulator is shown below. Example switching regulator feedback loop. The above example is probably the simplest case of a regulation circuit where the output is adjusted by modulating a duty cycle. Here, a ramp voltage is used with a positive feedback comparator. WebDec 20, 2024 · How does a comparator work? A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side; VDD in the illustration) or a 0 (the voltage at the negative side) to indicate which is larger. The circuit amplifies the voltage difference between Vin and VREF, and outputs the result at Vout.
