Abstract
In this paper we investigate the noise behaviour of electromagnetic interference (EMI) improved integrated folded cascode amplifier input stages. In this context we compare seven EMI improved differential input pair structures, using concepts of filtering, linearisation and compensation in terms of their noise behaviour. We pay special attention to the differences in the behaviour of the structures at the design stage and the layout stage, where we also considered layout-specific parasitics that can affect circuit and noise performance. We analyse the structures in terms of input referred noise, noise contribution of different devices, contributions of layout parasitics to noise, differential mode gain, gain-bandwidth product (GBWP) and power.
