Calibrating amplifiers and ADCs in
M. Ganesh Raaja & Pushek Madaan, Cypress Semiconductor Corp.,
2012. The FmcAdc100M14b4cha implements double point calibration in the
production test, using an external calibration voltage. It should be
possible to implement Correlated Double Sampling (CDS) to
dynamically compensate for offset errors. No internal calibration
voltage is present.
