Lowering Centre Frequency of Bandpass Filter using VCII based Capacitance Multiplier

The author hereby presents a bandpass filter circuit designed using voltage conveyors. The goal of this study is to lower center frequency obtained by bandpass filter to a very low frequency range. The study underscores the role of capacitance multipliers in achieving the intended goal. Resistors used in the capacitance multiplier allow the adjustment of the multiplication factor. The study has been implemented on 180nm technology. The outcome of this study could extend to various domains including biomedical applications requiring effective low frequency signal filtering.
