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 cascade topology, and has been designed in a 0.18 mu m UMC CMOS process. Measurements illustrate that the modified recycling folded cascade exhibits an increased EMI immunity while preserving a satisfactory frequency response.
