Abstract
A comparator control circuit includes a current source, a first input unit, a second input unit, switches, and a ground terminal. The current source generates an input current. The input current is divided into a first current flowing through the first input unit and a second current flowing through the second input unit. The first input unit receives a signal voltage. The second input unit receives a reference voltage. The first input unit and second input unit are coupled to the current source. The switches include a first switch and a second switch. The second switch has a control voltage. The ground terminal is coupled to the switches. When the first input unit is at high-level, the first switch is switched off and second switch is switched off by the control voltage to stop the second current flowing from the second input unit to the ground terminal.
