Control method for an output signal in a voltage-current change device fed with a reference voltage alters an incoming voltage signal to a current signal

摘要

A reference voltage (UREF) is fed to a voltage-current change device. A voltage signal (I,IX) on the incoming side is turned into a current signal. The reference voltage adjusts a zero-signal output current. An adjusting device links to a reference input and, on an input, detects an envelope for a signal that is modulated regarding amplitude. An independent claim is also included for a voltage-current change device with a voltage input, a current output and a reference input.
