Abstract :
A model is proposed for the input-output nonlinearity and the gain-frequency characteristic of a typical bipolar operational amplifier circuit. Using this model a closed-form expression is derived for the output signal of the operational amplifier circuit excited by a multisinusoidal input signal. Using this expression, the RFI demodulation in the operational amplifier circuit is predicted
