1. An electronic system for a system for neural applications, the electronic system comprising: at least one first connector element configured to connect the electronic system to a controller, the at least one first connector element configured to receive at least one electrical signal from the controller via one or more stimulation outputs; at least one second connector element configured to connect the electronic system to a lead configured to deliver neural stimulation; an integrated passive device comprising a substrate and at least one passive electronic component arranged one of on or in the substrate; a biasing circuit configured to provide a DC bias voltage to the substrate of the integrated passive device; and at least one leakage current detection circuit configured to measure at least one of a current of the bias voltage or a change in the DC bias voltage.
