摘 要：正Guided by the switch-signal theory,this paper introduces design theory suitable for current-mode CMOS circuits at switch *** this basis,the operations of current transmission switch used to describe the action of threshold-controllable switch in Schmitt trigger are established,and a novel current-mode CMOS ternary Schmitt trigger with ternary output current or/and voltage signal is *** two hysteresis current values of ternary Schmitt trigger are controlled by only sizing the transistor aspect *** main properties of the circuit are its simple structure,fully adjustable hysteresis and suitable for low-voltage applications.A design example and the HSPICE simulation results with a power supply of 1.5V are given.
