Abstract

Disclosed are a capacitive sensor, a sensing device, a sensing system, and an electronic device. The capacitive sensor comprises multiple sensor units. The sensor units comprise sensor electrodes and sensor circuits. The sensor electrodes are capable of coupling to a target object in a capacitive manner and are used for loading a reference signal. The sensor circuits comprise differential paired transistors. The differential paired transistors are used for, in response to a change in the reference signal on the sensor electrodes due to being approached or touched by the target object, correspondingly generating two different second alternating current signals. A sensing signal outputted by the capacitive sensor is of increased stability. The sensing device and the sensing system provided with the capacitive sensor are accurate in terms of sensing accuracy. The electronic device provided with the sensing device or the sensing system improves user experience.
