Analog-to-digital converter system with amplifier gain calibration

摘要: An analog-to-digital converter system 10 is provided that comprises two separate banks of capacitors are configured with a single operational amplifier 30 for each stage 29 within the 10. The used in an interleaved fashion to simultaneously digitize analog input voltages and sample reference voltage V REF enable digitization gain error associated operation 30. This can be combined raw digital output using arithmetic logic unit 18 result calibrated
