摘要
A logic gate section of a Schmitt trigger circuit has first and second nodes to which variable bias voltages are applied. A first bias control IGFET is connected between the first node and a first potential terminal. A second bias control IGFET is connected between the first node and a second potential terminal. A third bias control IGFET is connected between the second node and the first potential terminal. A fourth bias control IGFET is connected between the second node and the second potential terminal. A control signal to the gates of the first and fourth bias control IGFET's is provided by the Schmitt trigger input signal and the control signal to each of the gates of the third and fourth bias control IGFET's is provided by the Schmitt trigger feedback connection of two series-connected inverters.
