Picture 1 shows an amplifier made up ofμA709 and others. In this circuit, VT1 forms step attenuator which is regarded as a control part of automatically gaining. It is used to rectify and feedback the peak valve of its gate bias and connected to the negative feedback circuit of operating amplifierμA709.Feeback generated through R1 is used to make up nonlinear distortion of VT1.
