Abstract:
1. An amplifier comprising: a current conveyor having an input y, an input x, and an output z, wherein current at input x is related to current at output z by a current gain, and wherein voltage at input x is substantially equal to voltage at input y; a first input voltage line connected to input y of the current conveyor; a second input voltage line connected to input x of the current conveyor through a first resistive element; a second resistive element connecting output z of the current conveyor to ground; an output voltage line connected to output z of the current conveyor; a first input buffer having a non-inverting input and an output, wherein the second input voltage line is connected to the non-inverting input of the first input buffer, wherein the output of the first input buffer is connected to input x of the current conveyor through the first resistive element, and wherein the first input buffer has a first voltage gain; and a second input buffer having a non-inverting input and an output, wherein the first input voltage line is connected to the non-inverting input of the second input buffer, wherein the output of the second input buffer is connected to input y of the current conveyor, and wherein the second input buffer has a second voltage gain.
