Abstract: A digital-analog current converter receives, at input, a succession of bits of a binary signal and delivers, at output, sampled by a clock signal, a positive or negative current depending on the state of the input bit. The converter comprises at least one circuit to control the build-up time of the output current of the converter, comprising a capacitor and a circuit to charge this capacitor controlled by the clock signal. The build-up time is controlled by the charging of a capacitor at a constant current up to a reference voltage. The circuit to control the build-up time of the output current may comprise at least two reference voltages, the capacitor being charged and then discharged between these two voltages. The build-up time of the output current is then the sum of the time taken to charge the capacitor and the time taken to discharge the capacitor.
