Abstract

A semiconductor device comprising a substrate and an electronic circuit thereon is described. The electronic circuit comprises a first voltage provider node, a second voltage provider node, and an intermediary node connected to the first and second voltage provider node by a first and second network with a first and second resistance, respectively. The substrate is susceptible to conducting a substrate current. The semiconductor device further comprises a substrate current sensor. 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 vice versa. Similarly, 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 vice versa.A method of operating a semiconductor device is also disclosed.
