Abstract

Qualitative performance of a two-stage amplifier, configured by coupling a CE amplifier with Darlington pair amplifier is critically analyzed. A significant enlargement in bandwidth on the cost of voltage and current gains is observed. This proposed two-stage amplifier may be quite useful for amplification of small signals up to the voltage range of 25mV and suitable for various analog electronics and communication applications.
