Patent ID: 7965210

Claim:
A closed loop slaving device for slaving a first component in a closed loop, an output of the first component forming an output of the closed loop, the slaving device comprising a second component having a multiplicative noise (β DAC ), wherein the closed loop comprises: a first combiner having: a first input forming a loop input, an input signal to the closed loop provided at the loop input; a second input to provide a compensation noise; and an output; a second combiner having a first input in communication with the output of the first combiner, and an output of the second combiner in communication with an input of the first component; and a loop return, an input of the loop return formed from the output of the closed loop, the input of the loop return in communication with an input of the second component, an output of the second component forming an output of the loop return, and the output of the loop return in communication with a second input of the second combiner, wherein: the compensation noise signal being substantially equal to the input signal of the closed loop multiplied by the multiplicative noise of the second component.
