Q. Describe the construction of a two stage RC coupled amplifier with diagram.
A cascaded arrangement of common-emitter transistor stages is shown above. The output Y1 of one stage is coupled to the input X2 of the next stage via a blocking capacitor Cb which is used to keep the d-c component of the output voltage at Y1 from reaching the input X2. The resistor Rg is the grid leak and the plate circuit resistor is Rp. The cathode resistor Rk, the emitter resistor Re, the screen resistor Rsc, and the resistor R1 and R2 are used to establish the bias. The bypass capacitors, used to prevent the loss of amplification due to negative feedback, are Ck in the cathode, Cz in the emitter, and Csc in the screen circuit. High frequency response is limited by the presence of junction capacitances.
