Avadh University, Faizabad (UP) INDIA - 224001 <p style="text-align: justify;">Two distinct Modifications are proposed in the conventional circuit of Triple Darlington amplifier by adding an extra biasing resistance RD. First amplifier completely removes the problem of poor response of Triple Darlington at higher frequencies as well as provides wide band frequency response for small signals. While, the second amplifier effectively widens the frequency band. Hence the proposed small signal amplifiers can be significantly used in various commercial electronics and communication circuits.</p> <p>&nbsp;</p> https://ultraphysicalsciences.org/paper/1083/ Small Signal amplifiers Darlington amplifiers Electronic Circuit Simulation
