Designing and Optimization to the Performance of Multi Stage Tuned Amplifier

This paper report describes the performance of a multi stage tuned amplifier. Tuning can be done to select only desired frequency and to get the required output. Single tuned amplifier selects the frequency equal to the resonant frequency. At resonant frequency it can provide higher impedance but it has few disadvantages like poor selectivity, poor bandwidth, and greater power loss in order to overcome these problems double tuned amplifier has been used. Double tuned amplifier has two tuning circuits and thus larger gain can be achieved by cascading double tuned amplifier. This cascade amplifier arrangement is beneficiary to improve the Q factor, selectivity, sensitivity, improved frequency response and less power loss.
