Comparator with Hysteresis

 

Description

Parameters

Description

The Comparator models an ideal comparator with hysteresis. The input impedance is infinite.

The output goes high when Vhys2<vpvn. It goes low when vpvn<Vhys2.

When the output is high, the output pin is connected to the high supply pin, hi, through a resistance Ron, and is connected to the low supply pin, lo, through a conductance Goff.

When the output is low, the output pin is connected to the high supply pin, hi, through a conductance Goff, and is connected to the low supply pin, lo, through a resistance Ron.
