Current-mode instrumentation amplifier error reduction circuit and method |
July 28, 2009 |
| A current-mode instrumentation amplifier (IA) error reduction circuit and method employs a current-mode IA topology and an auto-zero circuit. The IA receives a differential voltage (VINP-VINN) and produces differential DC currents (I.sub.DC1, I.sub.DC2) in response, which are summed to |
