Abstract
Embodiments of an active shielding device and method for active shielding are disclosed. In an embodiment, an active shielding device includes current sources configured to generate currents, an analog wire shield unit connected to the current sources, switches connected between the current sources and the analog wire shield unit, a current to voltage converter connected to the analog wire shield unit and configured to generate a voltage in response to the currents that are generated by the current sources and a digital control sequence for the switches, a voltage comparator connected to the current to voltage converter and configured to compare the voltage that is generated by the current to voltage converters with a reference voltage, a digital active shielding unit connected to the current sources, digital logics configured to process the digital control sequence before conducting the digital control sequence through the digital active shielding unit and after conducting the digital control sequence through the digital active shielding unit to generate a first processing result signal and a second result signal, and a digital comparator configured to compare the first processing result signal with the second result signal.
