Abstract
A noise analysis of a three opamp instrumentation amplifier is presented. The results, although not surprising, do give a theoretical basis for designing low noise instrumentation amplifiers. Using MAPLE, a symbolic computation package, known sources and loads are connected to the amplifier and the outputs are determined. These outputs are then passed to MAPLE subroutines which have been developed to determine the amplifier noise characteristics by manipulating the sources and loads. Experimental measurements to confirm the analysis and recommendations to minimize the noise are also provided.
