Abstract
A device, including a first current supply configured to provide a bias current to a load and a main current supply having a source terminal coupled in parallel with the load and configured to reduce a current value to the load below the bias current, is provided. The device includes a termination resistor coupled in series with the source terminal of the main current supply and configured to receive current from the source terminal of the main current supply when the source terminal of the main current supply is activated. The device also includes an auxiliary current supply having a sink terminal coupled to the termination resistor at a common node, and configured to maintain the common node at common mode voltage when current flows from the source terminal of the main current supply to the sink terminal of the auxiliary current supply and through the termination resistor.
