Abstract
An amplifier circuit in particular configured as an operational transconductance amplifier has signal paths switched in parallel to the individual transversal branches or signal paths, which can be alternatively activated and deactivated with the aid of suitable switching means (1, 2), so that without essentially changing the dynamic characteristics of the amplifier circuit switching over is possible by activating these parallel-switched additional signal paths or the transistors (M3.2–M12.2) contained in these from normal operation (A) into an operation (B) with, for example, a higher clock frequency in comparison to normal operation or for operating with higher loads in comparison to normal operation.
