US Patent 10333510 System and method for biasing an RF switch

In accordance with an embodiment, a circuit includes an RF switch, a leakage compensation circuit having a bias port and a reference port, a replica resistor coupled between a reference node and the reference port of the leakage compensation circuit, and a bias resistor coupled between the bias port of the leakage compensation circuit and a load path of the RF switch. The leakage compensation circuit configured to mirror a current from the bias port to the reference port, and apply a voltage from the reference port to the bias port.
