A biasing device can supply a bias voltage to bias-able element by coupling a bias circuit to the bias-able element, coupling a state adjusting device to the biasing circuit, configuring the state adjusting device to 1) increase an initial biasing voltage by a first amount when an intermediate voltage threshold exceeds a voltage drop across the bias-able element and 2) increment the increased initial bias voltage by a second amount, where the second amount is a fraction of the first amount, until the voltage drop across the bias-able element substantially equals a predetermined bias voltage. The bias circuit of the biasing device can include a variable resistance, which is controlled by the state adjusting device and configured to vary the biasing voltage, in series with the bias-able element. The variable resistance can include a first variable resistance coupled in series to a first terminal of the bias-able element and a second variable resistance coupled in series to a second terminal of the bias-able element.
