Description
The differential amplifying circuit utilizes the symmetry of the circuit parameters and the negative feedback to effectively stabilize the static operating point, and amplifies the differential mode signal to suppress the common mode signal. It is widely used in the input stage of the direct coupling circuit and the measuring circuit.
