Abstract: A circuit may be configured to reduce current leakage. The circuit may include a bias generator, a charge interface, and a charge controller. The bias generator may be coupled to a first voltage source and configured to generate a first current and provide a first voltage. The charge interface may be communicatively coupled to the bias generator and configured to mirror the first current into a second current. The charge controller may be communicatively coupled to the charge interface and configured to receive the second current from the charge interface and provide a second voltage. The bias generator may be further configured to perform an ultra-low leakage switching operation in which the first voltage is switched to a third voltage while reducing a first possibility of band-band tunneling leakage at the charge interface.
