Abstract:
A pressure sensing detection circuit and a driving method thereof, an electronic device. The pressure sensing detection circuit includes: an excitation signal circuit, configured to output an alternating current voltage signal; a pressure sensing circuit, configured to sense a magnitude of an external pressure and output a detection voltage signal under excitation of the alternating current voltage signal; and a phase detection circuit, configured to detect a phase change value of the detection voltage signal and convert the phase change value into a voltage value.
