Abstract:
An instrumentation amplifier configured for providing high common mode rejection is described and includes an input differential stage configured to receive a differential input voltage and a folded cascode amplifying stage configured to receive output current mode signals provided from the input differential pair. A plurality of feedback networks is provided to improve the input stage. The amplifier may operate to provide an enhanced common mode rejection ratio of a single gain block in the instrumentation amplifier. In some examples, the circuitry may have a differential folded cascode amplifying stage which permits high precision and low distortion of amplified signals without degrading the common mode rejection ratio.

Claim (Index 9):
The instrumentation amplifier according to  claim 8 , further comprising:\n a current buffer stage including a pair of transistors, each of the pair of transistors being configured as a current source to a corresponding transistor of the folded cascode amplifying stage, the current buffer stage being configured to provide a portion of the sum of the output signals to input terminals of a folded cascode stage; and a dependent current source connected to the current buffer stage, the dependent current source being configured to provide cancellation current to input terminals of folded cascode stage.
