Title: Method for controlling A/D converter
Inventor: KITAGUCHI YUJI
IPC: H03M1/38
Filed: 1997-07-12
Granted: 2000-07-21
Abstract: A method of controlling an analog-to-digital (A/D) converter for converting an input voltage into digital data. The conversion process includes charging a capacitor with the input voltage to be converted into a digital data, and disconnecting the input voltage from the capacitor. A control circuit to a digital-to-analog (D/A) converting unit furnishes a reference voltage, generated according to digital data. The reference voltage is applied to the capacitor by turning on a switch connected between the D/A converting unit and the capacitor. New digital data to be furnished by the control circuit is determined according to a charged voltage on the capacitor. The D/A converting unit causes the reference voltage to be delivered to the capacitor to change to a new value according to the new digital data from the control circuit. Before the reference voltage begins a transition to a new value, the switch is turned off and kept off until the reference voltage from the D/A converting unit becomes stable at the new value.
