Abstract
A CMOS programmable gain amplifier ( ) is disclosed which provides exponential gain using a single gain element ( ) which may be implemented in either bipolar or CMOS technology. An embodiment of the present invention includes a first and second sampling impedance ( ), a first and second feedback impedance ( ) and a gain element ( ). The gain element ( ) having an inverting input, a non-inverting input and an output. The inverting input connects to the first sampling impedance ( ). The non-inverting input connects to the second sampling impedance ( ). The first feedback impedance ( ) connects between the inverting input and the output. The second feedback impedance ( ) connects between the non-inverting input and the output.
