A 0.01% linear instrumentation amplifier
C. Nelson · 1980
The use of combined resistive and current mode feedback in an instrumentation amplifier with 8nV/\sqrt{Hz}input voltage noise, 2nA input bias current and 0.01% linearity will be reported. Laser trimming of silicon-chrome resistors affords 20μV input offset voltage and 0.2μV/°C drift.
