Sorry, there is no phase sensitive resistor.

There are: Phase-sensitive detector circuit:

The phase-sensitive detector circuit is a detector circuit with the ability to identify the phase and frequency selection of the modulated signal

In phase-sensitive detectors The function of the shaping circuit is to convert the input sine wave into a square wave so that the electronic switch in the phase-sensitive detector can work normally.

In layman terms, it refers to the use of the wave peak characteristics of alternating current to output a signal. This signal is then converted into the required DC signal, and an intermittent analog signal is output at a specific time.

Also Phase sensitive detection. The original poster can search on Baidu himself. No more plagiarism here.

Hope this can be helpful to you
