ABSTRACT:
A folding amplifier is proposed for the construction of an A/D converter to which a current signal is fed as the input signal and from which a current difference signal is derived using a reference current. This current difference signal is fed to a first current-controlled current source, which is designed as a current mirror, and also to a second current-controlled current source, whereby the first current source takes over this current when the current difference signal has a positive sign and if the current difference signal has a negative sign the second current source takes over this current. The outputs of the first and second current-controlled current sources are fed to the output of the folding amplifier. Preferably, this folding amplifier is provided with a third current-controlled current source with sign reversal whose input is connected to the outputs of the first and second current sources and whose output is a V-shaped output current signal.
