Abstract
The analog-to-digital converter includes a first stage in which a voltage to be converted is applied to the input of a first comparator. The first comparator delivers, on a first digital output, a first digital result representative of the comparison between the voltage to be converted and the comparison voltage. The first digital output is connected to a calculator of a first intermediate voltage. A second comparator compares the first intermediate voltage with the comparison voltage and delivers a second digital result on a second digital output terminal. The second digital output terminal is connected to a second calculator of residual voltage that is a function of the voltage to be converted, of first and second voltages and of the first and second digital results. The first calculator is formed by the second calculator.
