A New Circuit Model of Small-Signal Sziklai Pair Amplifier

SachchidaNand Shukla and Susmrita Srivastava
Abstract—A new circuit model of RC coupled small-signal Sziklai pair amplifier is proposed and qualitatively analyzed for the first time. The circuit of proposed amplifier uses a Sziklai pair with NPN driver and crops high voltage gain (237.916), moderate bandwidth (15.10KHz), fairly high current gain (712.075) and considerably low THD (0.73%) at 1mV, 1KHz input AC signal. This circuit can be tuned in specific audible frequency range, extending approximately from 1Hz to 20KHz. Tuning performance makes this amplifier circuit suitable to use in Radio and TV receiver stages. The qualitative and tuning performance of the proposed amplifier offers it a flexible application range as high voltage gain, high power gain and tuned amplifier. Tuning performance, variation of voltage gain with frequency and different biasing resistances, input and output noises at operating frequency, temperature dependency of performance parameters and total harmonic distortion of the amplifier are perused for providing wide spectrum to the qualitative studies. The proposed Sziklai pair configuration with NPN driver transistor can be attempted to fabricate a single pack transistor IC version of Sziklai pair. Proposed circuit is also free from poor response problem of small-signal Darlington pair amplifiers at higher frequencies and narrow-band response region for PNP driven small-signal Sziklai pair amplifier.

Index Terms—Small signal amplifiers, sziklai amplifiers, complementary darlington pair amplifiers.
