Abstract
A novel hysteresis tunable monolithic comparator circuit based on a 0.35 ${\mu}m$ CMOS process is suggested in this paper. To tune the threshold voltage of the hysteresis in the comparator circuit, two external digital bits are used with supply voltage of 3.3V. The threshold voltage of the suggested comparator circuit is controlled by 234mV by change of 4 digital control bits in the simulation, which is a close agreement to the analytic calculation.
