Abstract
A logic inverter using field-effect transistors of the 'normally off' or 'quasi normally off' type with relatively wide tolerance on the threshold voltage. It comprises a first half-stage comprising a field-effect transistor with low threshold voltage, whose source, instead of being connected to ground, is connected to the gate of a second transistor placed in a second half-stage in series with a diode which plays an essential role in the switching of the inverter.
