摘要: An algorithmic analogue/digital convertor using current rather than voltage as the signal is proposed. A 6-bit prototype was fabricated a standard 3 mu m CMOS process. The circuit exhibited sampling rate of 200 kHz while only requiring 0.38 mm/sup 2/ chip area and 4.65 mW power, making it well suited for use in larger VLSI systems.
