Abstract

Highlights: Instrumentation amplifier input stage with an increased immunity to electromagnetic interference. Measurements corroborating the simulations of this circuit. Fundamental derivations of the proposed modified recycling cascode input stage. Abstract: This paper presents a folded cascode CMOS instrumentation amplifier input stage with an increased immunity to electromagnetic interference (EMI): this structure is based on a recycling folded cascode topology, and has been designed in a 0.18 μm UMC CMOS process. Measurements illustrate that the modified recycling folded cascode exhibits an increased EMI immunity while preserving a satisfactory frequency response.
