Abstract
A method and apparatus for increasing the bandwidth of an operational amplifier and including a capacitor being connected across the inverting and non-inverting inputs of the operational amplifier and further including a feedback circuit connected from the output to one of the inputs, the inverting input, and wherein the value of the capacitance is selected such that the time constant of an RC network including the capacitance and the feedback circuit impedance is proportional to the inverse of the product of the closed loop gain and a factor .beta. which equates the absolute value of the gain at two different frequencies.
