摘要： The analog-to-digital converter comprises a first stage in which a voltage to be converted is applied to the input of a first comparator. The first comparator delivers a first digital result representative of the comparison between the voltage to be converted and the reference voltage on a first digital output. The first digital output is connected to means for calculating a first intermediate voltage. A second comparator compares the first intermediate voltage with the reference voltage and delivers a second digital result on a second digital output terminal. The digital output terminal is connected to second means for calculating a residual voltage according to the voltage to be converted, the first and second voltages and the first and second digital results.

摘要： The acquisition circuit comprises a second and third electronic switch connected in series between a photodetector and a first input terminal of an amplifier. A reference voltage is applied to a second input terminal of the amplifier, the reference voltage being applied between the photodetector and the second electronic switch by means of a fourth electronic switch. An integration capacitor and a first electronic switch are connected in parallel between the first input terminal and an output terminal of the amplifier. A buffer capacitor is connected between a common terminal of the second and third electronic switches and a secondary voltage. The electrical capacitance of the buffer capacitor is at least equal to that of the integration capacitor.
