20090322576	SIGMA-DELTA MODULATOR - The present invention relates to a sigma-delta modulator to convert an analog signal into a digital signal using an analog-to-digital converter slaved in a closed loop. The undecided bits at the output of the analog-to-digital converter are assigned the same values in the digital output signal from the modulator as in the digital signal returned to the input of the modulator.	12-31-2009
20100060499	CONTROL CLOSED-LOOP DEVICE AND SIGMA-DELTA MODULATOR - The present invention relates to a device for slaving a first component in a closed loop, a second component in the return circuit to the loop input having a multiplicative noise. It also relates to a sigma-delta modulator making it possible to convert an analog input signal into a digital output signal on the basis of an analog-to-digital converter slaved in a closed loop using this device. A compensation noise is added to the input signal of the slaving loop, the compensation noise being substantially equal to the input signal of the slaving loop multiplied by the multiplicative noise of the second component.	03-11-2010
