In this paper, we present the design and implementation of a filter for low-noise applications. The filter was designed using the methods of impedance and frequency scaling. It was built around a general-purpose operational amplifier (m741) as the only active component with a centre frequency of 200Hz, a centre frequency gain of 16.00, a quality factor of 3.9, a bandwidth of 52Hz and a noise figure of 2.00. Specifically, it has been designed as a first stage in a low-noise amplifier (LNA) to be used for the measurement of atmospheric electric field.
