| Abstract: | A small-signal
modified Sziklai pair (complementary
Darlington pair) amplifier is proposed with an additional biasing resistance in
the circuit. The proposed amplifier produces significantly high voltage gain
with narrow bandwidth. Poor response of conventional Darlington
pair amplifiers at higher frequencies is found to be absent in the proposed
amplifier circuit. Variations in voltage gain as a function of frequency and
different biasing resistances, bandwidth and total harmonic distortion of the
amplifier have also been studied. Proposed amplifier may be useful for various
analog communication applications. |
