Abstract
A successive approximation ADC with nonlinear characteristic is presented as an effective method for sensor linearization. Drastic simplification of the ADC structure was obtained by implementing a piece wise linear approximation of the required non linear curve. The design and simulated performance of an 8-bit prototype, applied to the linearization of a real flow sensor, are presented.
