Hall sensor circuit

The invention provides a Hall sensor circuit which comprises a sampling switch group, a first capacitor, a first amplifier, a second amplifier and a sampling circuit which are sequentially connected in series, the sampling switch group is used for being connected with a Hall sensor and receiving analog signals provided by the Hall sensor, and the sampling circuit outputs digital signals. A short circuit switch is connected between the input end and the output end of the first amplifier; the Hall sensor circuit further comprises a synchronous clock generator which is respectively connected with the sampling switch group, the short circuit switch and the sampling circuit and provides a first clock signal and a second clock signal for the sampling switch group to work. And providing a third clock signal to the short circuit switch and the sampling circuit for working. Therefore, the problem of imbalance of the comparator is solved, and the precision of the sensor is improved. 本申请提供一种霍尔传感器电路，包括依次串接的采样开关组、第一电容、第一放
