Abstract: This paper presents a technical analysis of three types of successive-approximation register (SAR) analog-to-digital converters (ADCs): a standard ADC, a neural self-routing ADC (NSR ADC), and an NSR ADC with an advanced internal diagnostics module (NS ADC AIDM). The study examines the characteristics of each type, including conversion time, conversion accuracy, multi-channel signal conversion capability, dynamic bit resolution adjustment, and accuracy diagnostics. The results show that both the NS ADC and NS ADC AIDM can achieve the required data acquisition speed (4 ms per cycle for the given example) in the control loop without using an external multiplexer. Moreover, implementing the AIDM reduces the number of individual measurements by approximately 25% while maintaining complete data integrity and increasing the measurement subsystem's response speed.

Keywords: neural self-routing analog-to-digital converter, self diagnostics, adaptive discretization, calibration curve, gas turbine engine, automatic control system, surge
