Abstract
An analog-to-digital conversion circuit and a method for calibrating an analog-to-digital conversion circuit are provided. A digital translation of an analog voltage is analyzed to determine a characteristic value of the analog voltage. A reference voltage, with which the digital translation is generated, is set to a value that is a minimum amount greater than the characteristic value. Additional embodiments include setting an offset voltage, with which the digital translation is also generated.
