Abstract :
The use of a monotonic ladder network in a two-stage n-bit flash A/D convertor is examined. The technique is verified by a 6-bit discrete ADC. High-speed and monotonic operation are theoretically impossible in a two-step flash converter with this technique. This method allows for a reduction in the required circuit die size, while maintaining the conversion speed of a flash A/D converter.
