Title:
SUCCESSIVE APPROXIMATION REGISTER ANALOG TO DIGITAL CONVERTER CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2011/151671
Kind Code:
A8
Abstract:
Techniques are generally described herein for analog to digital conversion. Some example ADC converters include a unit capacitor array coupled to a reference voltage, where the capacitor array includes multiple capacitors coupled to one another via multiple switches under control of a control block. A comparator, having a first input and a second input, is configured to receive a controlled voltage generated from the unit capacitor array and compare an analog voltage to the controlled voltage. The control block is configured to selectively open or close the switches, receive a comparison result from the comparator, and generate a digital output based on the comparison result. The control block is configured to control the switch timing of the unit capacitor array for reset, pre-charge, charge redistribution, and comparison phases, where a passive charge redistribution method may be utilized.
