A novel analog-to-digital converter (ADC) architecture based on the principle of successive approximation register (SAR) is described. An algorithm is developed, which allows the conversion of high voltage input signals with a low voltage analog core and without a significant attenuation of the input signal. With this technique the Signal-to-Noise Ratio(More)
An analog-to-digital converter (ADC) compares the input voltage V<sub>in</sub> with a reference voltage REF to convert it into a digital word. The reference source must be able to drive the ADCs reference input; it needs to provide low noise, should be adjustable, stable over temperature and supply voltage and should not require external components. A novel(More)
