AmplifierWithOpAmpDetailed

Inverting operational amplifier circuit built using a detailed op-amp model.

This circuit implements an inverting amplifier configuration utilizing an OpAmpDetailed component. An input signal, generated by input_signal1 (a sine wave with 12V amplitude, 1kHz frequency) and conditioned by voltage_source_1, is applied to the inverting input terminal of the operational amplifier via the input resistor (Rin = 10kΩ). The non-inverting input of the op-amp is connected to the circuit ground. The operational amplifier is powered by `voltagesource2(+15V) andvoltagesource3(-15V), which are driven byinputsignal2andinputsignal3respectively. The output of the amplifier is connected to a loadresistor2(10kΩ). The voltage gain of this inverting amplifier is primarily determined by the ratio of the feedback resistorresistor1` (Rf = 20kΩ) to the input resistor. Given the component values $R_{in} = 10k\Omega$ (parameter R of resistor) and $R_f = 20k\Omega$ (parameter R of resistor1), the ideal gain is -2. The behavior of OpAmpDetailed will introduce non-ideal characteristics.
