Claims
- 1. A phase detector, comprising:
(A) a load circuit coupled to (1) a power supply and (2) a first node and a second node, wherein the first and second nodes form an output of the phase detector; (B) a capacitive circuit having (1) a first capacitor coupled to the first node and ground and (2) a second capacitor coupled to the second node and the ground; (C) a first circuit coupled to the first and second nodes for detecting a phase difference between a first signal and a second signal; (D) a second circuit coupled to the first and second nodes for detecting the phase difference between the first and second signals and for minimizing phase detection error of the first circuit such that the phase difference between the first and second signals can be detected with minimized phase detection error, wherein each of the first and second circuits receives the first and second signals and a reference signal.
