AIM:
To design an Inverting Amplifier for the given specifications using Op-Amp IC 741.
THEORY:
The input signal Vi is applied to the inverting input terminal through R1 and the non-inverting input terminal of the op-amp is grounded. The output voltage Vo is fed back to the inverting input terminal through the Rf - R1 network, where Rf is the feedback resistor. The output voltage is given as,
Here the negative sign indicates that the output voltage is 1800 out of phase with the input signal.
PROCEDURE:
1. Connections are given as per the circuit diagram.
2. + Vcc and - Vcc supply is given to the power supply terminal of the Op-Amp IC.
3. By adjusting the amplitude and frequency knobs of the function generator, appropriate input voltage is applied to the inverting input terminal of the Op-Amp.
4. The output voltage is obtained in the CRO and the input and output voltage waveforms are plotted in a graph sheet.
RESULT:
The design and testing of the inverting amplifier is done and the input and output waveforms were drawn.
