ANALYSIS OF TRANSISTOR FEEDBACK AMPLIFIERS Steps In.
Feedback Amplifiers Collection of Solved Problems Basic Description of Feedback.
A series circuit shares the same current among its components; a parallel circuit shares the same voltage. Power Sources in Series versus Parallel. An electrical source, such as a battery or power supply, creates a voltage difference across the circuit that drives electrical current. From Ohm's law, the greater the voltage, the greater the current.
The Negative Feedback Amplifier: in simple words, A feedback said to be negative feedback if the output signal is opposite in value or phase (i.e. out of phase or anti phase) to the input signal. The word amplifier here is slightly misguiding, this structure is not limited to only increasing the amplitude of a signal.

Welcome back to Electronics. This is Dr. Robinson. In this lesson, we are going to solve for the transfer function or the output voltage versus input voltage relationship for a circuit known as a two op-amp diff-amp or two op-amp differential amplifier. Let me begin by drawing the circuit schematic for the two op-amp, diff-amp.
There are different types of transistor amplifiers operated by using an AC signal input. This is interchanged between the positive value and negative value, hence this is the one way of presenting the common emitter amplifier circuit to function between two peak values. This process is known as the biasing amplifier and it is an important amplifier design to establish the exact operating point.
