Title: Type c interface single-pole double-throw switch circuit, analog switch chip and electronic device
Inventor: TAO HONGXIA
IPC: H03K17/51
Filed: 2020-08-10
Abstract: Provided in the present invention are a Type C interface single-pole double-throw switch circuit, an analog switch chip and an electronic device, which may generate a reverse bias voltage at two ends of a first diode. After the reverse bias voltage is applied to a PN junction, the capacitance value of the PN junction may be significantly reduced. Furthermore, the capacitance to ground at a COM point when a first field effect transistor (FET), i.e. an audio channel, is turned off may be effectively reduced, thereby preventing the reduction of the bandwidth of a digital channel due to excessive capacitance. Hence, on the basis of the present invention, the large size of the first FET and the high bandwidth of the digital channel may easily be simultaneously achieved, so that the THD performance of the analog audio channel and the bandwidth of the digital channel may easily be simultaneously improved, thus preventing conflict between the two.
