Description

Technical field [0001] The invention discloses an amplifier circuit with a three-stage amplification structure, and relates to the technical field of data processing. Background technique [0002] Operational amplifier (referred to as operational amplifier) ​​is a circuit unit with a very high amplification factor. In actual circuits, a certain functional module is usually combined with a feedback network. It is an amplifier with a special coupling circuit and feedback. The output signal can be the result of mathematical operations such as addition, subtraction, differentiation, and integration of the input signal. Since it was used in analog computers in the early days to realize mathematical operations, it was named "operational amplifier". The op amp is a circuit unit named from a functional point of view, which can be realized by a discrete device or in a semiconductor chip. With the development of semiconductor technology, most operational amplifiers exist in the form of...
