ABSTRACT:
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.
