Abstract
Dynamic properties of ADC time-impulse type with a coarse-fine reference system are analyzed. The concept of the acceleration coefficient of the transformation process is introduced, and its dependence on the number of discharges and the number of conversion steps is investigated. Recommendations for the choice of the parameters of the transducers are given. A technique is proposed for the optimal distribution of discharges over the conversion stages, which ensures the best dynamic properties of coarse-accurate converters. It is shown that the implementation of coarse-precision methods provides multiple acceleration of the conversion. The fastest rate increase observed in the transition from a single-stage to a two-step transformation.
