Abstract

This paper presents a low noise fully differential difference amplifier for seismic wave detection. Seismic waves generated due to earthquake have very low frequency and magnitude. It needs a low noise amplifier in the front end for further processes. This work presents a strategy for noise optimization in a FDDA using <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$g_{m}/I_{D}$</tex> method. It provide a easy technique to alter the corner frequency of noise and also exhibits a good matching between analytical and simulated results of unity gain bandwidth even in sub-micron technology. A Fully differential difference amplifier (FDDA) is designed using SCL-180nm technology and 1.8V supply.
