Abstract
An amplifier circuit for current amplification. An input stage is adapted to receive an input signal. At least one current multiplication stage is connected to the input stage. The current multiplication stage is adapted to receive a current signal from the input stage and to produce a multiplied output current signal at an output of the amplifier circuit. The current multiplication stage includes at least two current multiplication circuits connected to each other. Each current multiplication circuit is adapted to produce an output current signal essentially equal to the current signal from the input stage, such that the output current signal at an output of the amplifier circuit includes a sum of the current signals received at each current multiplication circuit. A method of improving linearity in an amplification circuit.
