提出了一种利用N路滤波器精确测量同频周期信号相位差的方法。它示出，使用N通道滤波器和可变延迟单元内的反馈电路允许精确测量的相位差的幅度的一个信号的二十个十年的范围。仿真结果表明，100 MHz输入信号的相位分辨率低于1°，幅度低至10 mV。该电路采用1.8 V电源供电时功耗为12.6 mW。
A technique for using an N-path filter to precisely measure the phase difference between a pair of periodic signals with the same frequency is presented. It is shown that using the N-path filter and a variable delay cell within a feedback circuit allows for accurate measurement of the phase difference for a two-decade range of amplitude of one of the signals. Simulations demonstrate sub-1° phase resolution for 100 MHz input signals with amplitudes as low as 10 mV. The circuit dissipates 12.6 mW from a 1.8 V supply.
