Basic feedback amplifier circuit diagram
The circuit consists of unipolar and bipolar transistors, voltage isconnected to negative feedback in series, and input impedance is high while output impedance is low, and the closed-loop gain is adjustable. This circuit structure is applicable for low-frequency or high-frequency signals, when the high-frequency signal works,it requires ceramic capacitors or polyester capacitors with low capacity to connect to the capacitors shown in figure in parallel, and it selects high-frequency transistors.
