ABSTRACT:
A Schmitt trigger circuit has a field effect transistor coupled between a first fixed potential and an output terminal, and a variable negative resistance circuit coupled between the output terminal and a second fixed potential; the gate of the field effect transistor and the control input of the negative resistance circuit are coupled to the input terminal of the Schmitt trigger circuit; wherein the negative resistance circuit includes a first field effect transistor coupled between the output terminal and the second fixed potential, and a gate coupled to an internal node; a second field effect transistor coupled between the internal node and the second fixed potential, and a gate coupled to the input terminal; and a third field effect transistor coupled between the first fixed potential and the internal node, and a gate coupled to the output terminal.
