Abstract
A voltage controlled oscillator comprised of a current controlled oscillator formed of a loop of serially connected inverters, the oscillator having a primary output at an output of one of the inverters for providing a primary pulse signal and a secondary output at the output of another inverter spaced from the one inverter by an odd number of inverters for providing a secondary pulse signal which is in antiphase to the primary pulse signal, apparatus for receiving the primary and secondary pulse signals and for providing an output signal which indicates the presence of a rising or falling edge to a corresponding primary or secondary pulse signal during a transmission time delay provided by the odd number of inverters.
