Comparator Hysteresis Calculator

Design comparators with hysteresis. Set threshold voltages and calculate feedback resistor values.

Supply Voltage (V)

V_ref (V)

High Threshold V_TH (V)

Low Threshold V_TL (V)

Pull-up Resistor R_pull (kΩ)

Input Impedance (kΩ)

Hysteresis: V_hys = V_TH – V_TL

Feedback R: R_h = R₂×V_s/V_hys
