QUALITATIVE ANALYSIS OF SMALL-SIGNAL WIDE-BAND TRIPLE DARLINGTON AMPLIFIER

摘要

Modification is proposed in the conventional circuit of Triple Darlington amplifier by adding an extra biasing resistance R_D This completely removes the problem of poor response of Triple Darlington and Darlington pair amplifier at mid range and higher frequencies. Proposed amplifier also provides a wide frequency band response for small signals and thus effectively used in various analog circuits.
