AIM:
To design a Non-Inverting Amplifier for the given specifications using Op-Amp IC 741
THEORY:
The input signal Vi is applied to the non - inverting input terminal of the op-amp. This circuit amplifies the signal without inverting the input signal. It is also called negative feedback system since the output is feedback to the inverting input terminals. The differential voltage Vd at the inverting input terminal of the op-amp is zero ideally and the output voltage is given as,
Here the output voltage is in 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 non - 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 Non-inverting amplifier is done and the input and output waveforms were drawn.
