Abstract

A phase alignment circuit which will take a square wave of constant period but indeterminate duty cycle and will transform it into a square wave of equal period and deterministic duty cycle, e.g. 50%. The preferred embodiment alternately charges and discharges two equal capacitors, and passes the resulting ramp voltages through a comparator to produce a square wave output with a 50% duty cycle.
