In this project about inverting amplifier, output voltage is fed back to input so as to cancel the effect of variation of temperature on voltage gain and improve [[wysiwyg_imageupload::]]stability of circuit with respect to temperature variations.Inverting inputs are more preferred than the non-inverting ones due to the main benefit of stability. Inverting amplifiers, hence, even though provide less gain, are used for more applications. From various electronic circuits such as integrator or differentiator, inverting amplifiers are used in designing filters for communication circuits.Without much change in the circuitry, inverting amplifiers can be made to work from AC to DC mode or vice versa. Hence, it becomes an easy task to design the circuits without giving much attention to the obvious power concerns. Let’s find out how to make an inverting circuit by using a transistor, a DC battery source and a few passive electronic components.
