ABSTRACT:
A Schmitt trigger circuit has an input device and an amplifier. The input device has a current adder device having a P-type current mirror circuit and a N-type current mirror circuit connected in parallel. The P-type current mirror circuit has a positive constant current source for converting an external input signal to a positive constant current and a first output current control transistor for controlling an output current from the positive constant current source. The N-type current mirror circuit has a negative constant current source for converting the external input signal to a negative constant current and a second output current control transistor for controlling an output current from the negative constant current source. The amplifier amplifies the output signal from the input device and generates the feed-back control signal to be used for controlling and driving the first output current control transistor and the second output current control transistor.
