Abstract: – Feedback is a method in which a portion of the output returned to the input in order to modify the characteristics of the device. Feedback can applied to transistor amplifier circuits to modify their performance characteristics such as gain, bandwidth, input and output impedance etc.. There are number of ways by which a signal can be derived from output and can be returned to input. 1. In this paper I will analyze and compare the different characteristics of Feedback and without feedback amplifier circuit of BJT. 2. After that I will compare the feedback amplifier of BJT with feedback amplifier of CMOS. 3. Different waveforms will be finding out by manipulating different parameters in the circuit design and mathematical calculation and comparison will be done.
