초록

In this paper, a new phase detector which can detect phase difference of variable input frequency and represent as a DC voltage is designed. The proposed phase detector has detection range from $-180^{\circ}$ to $180^{\circ}$. It is implemented by digital electronic circuit. It operates from 125 kHz to 4 MHz frequency of input signal and it's maximum phase error is $360/256^{\circ}$.
