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.

Abstract: Techniques for supplying a bias current to a load are provided. In certain examples, a circuit can include a level-shift capacitance, a current source, and a load configured to receive a bias current in a first state of the circuit. The current source and the level-shift capacitance can be coupled in series between the load and a supply voltage in the first state. In some examples, during a second state of the circuit, the level-shift capacitance can receive charge, and can be isolated from one of the load or the current source.
