Abstract
A ping-pong-pang auto-zeroed and chopped current-feedback instrumentation amplifier (CFIA) uses three dynamically-matched input stages to achieve 0.04% gain error, a 2.5× improvement over prior art. Its 4 μV offset and 28 nV/√Hz noise are achieved at 3.5× less supply current than a comparable ping-pong auto-zeroed CFIA.
