Abstract
A shared path phase detector circuit for receiving a reference clock and an oscillator clock, the phase detector circuit providing an output signal for indicating a magnitude difference between a phase of the reference and oscillator clocks. The output signal is independently derived from the leading or lagging edge relationship of the reference and oscillator clocks. The output signal does not describe which signal leads, but only the width magnitude difference. The design provides a single path over which the output signal travels, without feedback, such that the circuit dependencies are greatly reduced.
