<p>A comparator circuit has a switching arrangement between first and second input branches. Second transistors of the first and second input branches (which would normally be the main current mirror transistors in a conventional comparator circuit) have their gates coupled together, and selectively connected to the first or second intermediate voltages of the input branches by the switching arrangement. The digital output voltage of the comparator circuit is used to control the switching arrangement, so that a feedback mechanism is implemented.</p> |
