<p>The present invention is about an Amplifier circuit (300, 400, 500, 600) for current amplification. The amplifier circuit (300, 400, 500, 600) comprises: an input stage adapted to receive an input signal; at least one current multiplication stage connected to the input stage; where the current multiplication stage is adapted to receive a current signal (ls?gnal) from the input stage and produce a multiplied output current signal (Iout) at an output of the amplifier circuit (300, 400, 500, 600). The current multiplication stage comprises at least two current multiplication circuits connected to each other, where each current multiplication circuit is adapted to produce an output current signal (Isignal) essentially equal to the current signal (Isignal) from the input stage, such that the output current signal (Iout) at an output of the amplifier circuit (300, 400, 500, 600) comprises a sum of the current signals (Isignal) received at each current multiplication circuit. Also a method of improving linearity in an amplification circuit is described.</p> |
