Abstract:
A silicon-on-insulator (SOI) complementary metal oxide semiconductor (CMOS) Schmitt trigger circuit with controllable hysteresis comprising:a stack of a plurality of field effect transistors (FETs) connected in series between a voltage supply and ground; an input applied to a gate of each of said stack of said plurality of field effect transistors (FETs); said stack of a plurality of field effect transistors (FETs) providing an output at a junction of a predetermined pair of said plurality of field effect transistors (FETs); at least one feedback field effect transistor (FET), each feedback FET having a source coupled a junction of a predefined pair of said plurality of field effect transistors (FETs) and having a gate coupled to said output; and a FET floating body of each of said stack of said plurality of field effect transistors (FETs) being connected to a voltage supply rail.
