  • Offset reduction in a zero-detect circuit
    Patent number: 5623220
    Abstract: A zero-crossing circuit and method, in which the sign of inputs to a comparator is reversed after each zero crossing of the input signal. This means that delay introduced by the comparator does not affect the duty cycle of the output signal, so precision synchronization remains possible.
