Abstract
An A/D converter that settles the converted digital result requiring no timing signal for synchronously-triggered conversion operation is disclosed. The A/D converter converts analog signals into digital signals in a limited number of rippling feedback operations in short time delay periods utilizing a simple circuit configuration that includes a network of parallel comparators. Each of the comparators is fed with a corresponding voltage reference supply by a resistor network. Each of the resistor networks includes series connections of resistors and a corresponding switch means that reflects the status of a determined data bit of the converted data. The circuitry configuration is relatively simply in structure and settles to a converted digital data in short periods of time that requires no synchronizing clock signal.
