Abstract
Aspects of the disclosure provide a circuit having a filter circuit and a controller. The filter circuit drives a load circuit having different input impedances under different operation conditions. The filter circuit is configured to have a first output circuit coupled with a first resistor and a second output circuit coupled with a second resistor. The controller is configured to generate control signals to select one of the first output circuit and the second output circuit based on an operation condition of the load circuit.
