Linearity Analysis in Continuous and Switched Capacitor Instrumentation Amplifier Architectures
This paper is a comparative study of different instrumentation amplifier architectures to be employed for
monitoring cell voltages in battery monitoring systems. The different instrumentation amplifier architectures are analyzed
based on swing and linearity. Improvements in the existing architecture which can enhance linearity and can ease the opamp
design is also suggested.
