Abstract

The use of a PSpice Model of BJT and JFET with their hybrid combination in Sziklai pair topology to design small-signal amplifiers is proposed.

The proposed amplifier will amplify low magnitude signals in a frequency range of 3.035Hz to 93.808Hz, with a maximum voltage gain of 30.41, maximum current gain of 43.05, and THD of 2.44%.

The possibility of using the proposed amplifier circuit in EEG, seismometers, and underwater submarine communication circuits is explored in this feature.

The proposed circuit's qualitative behaviour, such as temperature dependence, noise behaviour, the effect of changing biassing resistances and capacitors, small-signal analysis, and so on, is also investigated to see how it performs in various environments.
