Abstract :
A CMOS current Schmitt trigger whose hysteresis is independent of process parameters, transistor dimensions and power supplies is described. The hysteresis is determined by two currents and is adjustable over the range of the input current. The circuit function can be extended to a two-input current comparator with adjustable hysteresis.
