Claim:
1. A semiconductor device, comprising a substrate and an electronic circuit formed at least partly on or in the substrate; wherein the electronic circuit comprises a first voltage provider node, a second voltage provider node, and an intermediary node, wherein the intermediary node is connected to the first voltage provider node by a first network having a first resistance and to the second voltage provider node by a second network having a second resistance, the resistance between the intermediary node and the first voltage provider node being the first resistance and the resistance between the intermediary node and the second voltage provider node being the second resistance; the substrate is susceptible to conducting a substrate current, which is a variable spurious electrical current and the semiconductor device further comprises a substrate current sensor connected to the substrate and arranged to sense the substrate current; the first network is arranged to reduce the first resistance in response to the substrate current sensor signaling an increase of the substrate current and to increase the first resistance in response to the substrate current sensor signaling a decrease of the substrate; and the second network is arranged to reduce the second resistance in response to the substrate current sensor signaling an increase of the substrate current and to increase the second resistance in response to the substrate current sensor signaling a decrease of the substrate.
