Variable Precision Tandem Analog-to-Digital Converter (ADC)
<p>This paper describes an analog-to-digital signal converter which varies its precision as a function of input slew rate (maximum signal rate of change), in order to best follow the input in real time. It uses Flash and Successive Approximation (SAR) conversion techniques in sequence.</p> <p>As …
