A semiconductor device having an integrated circuit of which a region of one conductivity type is charged by supplying charge carriers from a zone of the opposite conductivity type to an inversion layer formed in the said region below a field electrode at which a voltage is set up. When the voltage is switched off, a part of the charge carriers recombine in the said region. According to the invention, the charge carriers are supplied from a supply conductor and an electronic switch is present between said conductor and the inversion layer, which switch prevents the flow back of charge carriers to the supply conductor when the inversion layer disappears.

Charge pump substrate bias generator

Write-in and/or read out amplifier for a capacitive source of logic signals, wherein the input of an inverting amplifier stage including insulated-gate field effect transistors is, in a first phase, connected to the output by a first switching unit and subsequently connected by a selection unit to the capacitive source, whereupon the charge on the input is restored by a third switching unit.
