Abstract
According to a first aspect of this disclosure there is provided a voltage controlled current path. The voltage controlled current path comprises a first stage arranged to conduct current once the voltage at an input node of the first stage exceeds a threshold value. The amount of current that passes through the first stage is a function of the voltage at the input node. A second stage is arranged to pass a current that is a function of the current passing through the first stage.
