Disclosed is a sensor unit of a capacitive sensor. The sensor unit comprises a sensor electrode and a sensor circuit. The sensor electrode is capable of coupling to a target object in a capacitive manner and is used for loading a reference signal. The sensor circuit comprises differential paired transistors. The differential paired transistors are associated with the sensor electrode and are used for, in response to a change in the reference signal on the sensor electrode due to being approached or touched by the target object, correspondingly generating two different second alternating current signals. The two different second alternating current signals outputted by the sensor unit are of increased stability. |
