Abstract
This paper proposes a design of Schmitt trigger circuit with multi-level signal or ternary Schmitt trigger. The circuit operates on current mode with two-current comparator circuits by using positive feedback technique, the threshold current can be generated. And the last stage is V-I converter uses to produce and combine each hysteresis loop as the ternary Schmitt trigger operation. All results have been verified by simulating on PSpice based on ES2 technology model.
