The inverting amplifier with T-feedback network can be used to obtain a high gain without a small value for R4 or very large values for the feedback resistors. An amplifier electronic amplifier or informally amp is an electronic device that can increase the power of a signal a time-varying voltage or currentIt is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals producing a proportionally greater amplitude signal at its output.
