Abstract:
1. An amplification circuit amplifying an input signal to generate an output signal, said amplification circuit comprising: an amplifier amplifying said input signal, wherein a gain of said amplifier changes when amplifying said input signal; and a component provided across an output of said amplifier, wherein an impedance of said component does not chance when amplifying said input signal such that changes in an amplification factor provided by said amplification circuit are minimized when amplifying said input signal to generate said output signal, wherein said component comprises a resistor, and wherein said amplifier contains a first output terminal and a second output terminal, and wherein said resistor is connected to both of said first output terminal and said second output terminal, a feedback circuit across said amplifier, wherein a resistance value of said resistor is chosen using the equation: wherein said resistance=(1/S
