Patent number: 6621337Abstract: The invention relates to an amplifier circuit having a circuit input for a circuit input signal (Vin) to be amplified and an amplification zone for amplifying the circuit input signal (Vin). The invention provides that the amplification zone comprises two amplifiers (OPV1, OPV2), each of which is countercoupled, and which the circuit input signal (Vin) is fed in parallel, and the amplifier outputs of which are or can be connected with a circuit output to provide a circuit output signal (Vout), wherein the amplification input zone of one of the two amplifiers (OPV1) is connected with the amplification input zone of the other of the two amplifiers (OPV2) by means of a further amplifier (A), in such manner that signal distortions at the two amplifier outputs (Vout1, Vout2) essentially cancel each other out. The amplifier circuit according to the invention thus provides for particularly power-efficient amplification of the signal.Type: GrantFiled: October 30, 2001Date of Patent: September 16, 2003Assignee: Xignal Technologies AGInventor: Martin Gröpl
