Inthe actual circuit, usually with some kind posed offunctional modules together. Opamp isaname from afunctional perspective, the circuit unit, can be realized bythe discrete devices, semiconductor chips can also beachieved among the The basic amplifier circuit opamp has four parts: the input stage, bias circuit, the middle class, the output level. Ofwhich: the input stage: the key istodetermine the performance ofanopamp, asking him tozero drift, high input resistance, soare differential circuit; bias circuit: bias voltage provided atall levels, atall levels with the appropriate static operating point; the middle class: isthe signal voltage ofthe input stage output tobeamplified, usually mon-emitter stage amplifier circuits; output level: output stage isconnected directly to the load, sothat asufficient voltage discharge.
