Abstract
A switching network with trimmable resistors lies in a control loop of a voltage generator that can be switched off from the supply voltage by a logic device. The logic device and also the switching network are driven by the same signals. The circuit configuration can be used for trimming or switching off the output voltage generated by the voltage generator during the functional test. As many settings as possible for the output voltage can be tested by a small number of control signals.
