Abstract

This paper presents a very simple circuit of balanced two-stage current amplifier and regulated cascode (RGC) amplifier to realize a linear current-to-voltage conversion. It can accept very low currents in the nA range. The noise model and strategies for noise reduction are discussed. The circuit is designed for 0.18μm CMOS technology and verified by simulations.
