Semi-flash A/D converter with minimal comparator count |
| abstract |
This circuit and method provides an analog-to-digital A/D converter with minimal power and minimal integrated circuit area. A circuit and a method for A/D conversion are provided which maintains performance, but which uses fewer comparators than the prior art. This is achieved by a semi-flash analog-to-digital, A/D, converter circuit with minimal comparator count. The design does not use any subtraction or multiplication operation. It utilizes fewer comparators than the prior art semi-flash A/D converters. The prior art designs use 30 comparators for an 8-bit semi-flash A/D converter while this invention uses 8 comparators. This circuit and method does not require any external Sample and Hold, S/H circuits. It is a hybrid between flash A/Ds and successive approximation A/Ds. |
