[Igor] made a VU meter with LEDs using 8 LEDs and 8 comparators. This is a fast way to get one of 8 bits to indicate an input voltage, but that’s only the equivalent of a 3-bit analog to digital ...
The noise‐shaping successive approximation register (NS‐SAR) analogue‐to‐digital converter represents an attractive hybrid architecture that merges the inherent energy efficiency and simplicity of ...
