Title: DC Amplifier with Suppressed Offset and 1/f Noise
Author(s): Josef Bajer   Karel Hajek            

Abstract: DC amplifiers have two significant disadvantages in comparison to AC amplifiers – a higher offset voltage and a 1/f noise. The objective of this work is to design and make the experimental sample of a DC amplifier with minimal noise (1 nV/√Hz) and bandwidth as wide as possible. Special techniques and components are used.

Keywords: 1/f noise, noise suppressing, DC amplifier.
