ABSTRACT:
A current supply circuit includes an input, a load terminal, a selectively activatable current regulator, a selectively activatable adjustable current source, and a comparator circuit. The input is configured to receive a first value signal. The load terminal is configured to provide a load current that is dependent on the first value signal. The current regulator is operable to, when activated, cause a first current to be provided through the load based on the first value signal. The adjustable current source is operable to, when activated, cause a second current to be provided through the load based on the first value signal. The comparator circuit is operable to generate a comparison of the first value signal and a second value signal, and is further operable to cause selective activation of one of the current regulator or the adjustable current source based on the comparison.
