Patent ID: 7183842

Claim:
An amplifier for amplifying an input signal comprising: a signal input node for receiving said input signal, a signal output node, an input gain device having a control pin coupled to said signal input node, and further having a first and second terminal for current flow therebetween and said first terminal comprising a drain and said second terminal comprising a source, an output gain device having an output terminal coupled to said signal output node, a voltage biasing resistor connected to said first terminal and said first terminal connected to the inverting input of said output gain device, a local feedback path coupled only between said output terminal and said inverting input of said output gain device and including a resistor in said local feedback path, an overall feedback path coupled only between said output terminal of said output gain device and said second terminal of said input gain device and including a resistor in said overall feedback path, current flow from said output gain device in said local feedback path linearizing local loop gain of said output gain device, current flow from said input gain device in said overall feedback path linearizing overall loop gain of said input gain device and of said amplifier, whereby a non-inverted output signal is produced at said signal output node proportional to said input signal voltage.
