Abstract:
1. An integrated circuit comprising a noise source, a sub-circuit, a noise medium capable of transferring noise signals from the noise source to the sub-circuit, a feedback circuit, having an input coupled to the noise medium at an input point on a first side of the sub-circuit and an output coupled to the noise medium at an output point on a second side of the sub-circuit, the first and second sides being opposite to one another relative to the sub-circuit, the noise source being coupled to the noise medium on said second side, comprising a further feedback circuit, with input and output coupled to the noise medium, so that an output of the feedback circuit is coupled to the noise medium closer to the input of the farther feedback circuit than to the input of the feedback circuit, the outout of the feedback circuit and the input of the further feedback circuit being mutually arranged so that undesired feedback of output signals from the output of the feedback circuit by the further feedback circuit is at least partially suppressed.
