ABSTRACT:
A closed loop slaving device is provided for slaving a first component, the slaving device including a second component having a multiplicative noise. A compensation noise is added to the input signal of the slaving device, the compensation noise being substantially equal to the input signal of the slaving device multiplied by the multiplicative noise of the second component. A sigma-delta modulator is also provided to convert an analog input signal into a digital output signal by use of an analog-to-digital converter slaved in the closed loop slaving device.
