Another application of auto-zeroing comparators is in the main control loop of a PWM system. The comparator in this application looks at the difference between a ...

There are many comparators that you can buy to provide quick (sub-microsecond) response when a large signal changes and crosses a threshold voltage, such as a reference voltage. Unfortunately, ...

Comparators are subject to input offset errors that can be either systematic or layout related. Two applications of comparators in a PWM controller are detecting when there is no current in the ...
