Circuit arrangement for continuous amplification change in inverting amplifier, has multiple impedances connectable via transistor to change circuit amplification, and integration units connected upstream from control inputs of transistor

摘要

The arrangement (10) has an operational amplifier (AMP) that comprises an output. An amplified input signal is provided at the output of the amplifier. The amplifier is fed back using a feedback network that comprises multiple impedances. The impedances are connectable via a transistor to change circuit amplification. Integration units (INT1 - INTN) are connected upstream from control inputs of the transistor.
