A method for calculating the total noise voltage at the output of inverting and noninverting amplifiers modeled using one- and two-pole differential gain expressions for the operational amplifier is developed. This method is adapted to deal with the case of a low-pass filter stage constructed using an operational amplifier modeled by a one-pole differential gain expression. The results obtained are presented in tabular form for convenient analysis and provide a basis for producing amplifier designs with improved noise performance
