Abstract:
An apparatus for active crosstalk cancellation in a multi-phase system, the apparatus comprising:a capacitive voltage divider associated with each individual phase of the multi-phase system, each capacitive voltage divider comprising a first capacitance between a high voltage conductor for the associated phase and a junction point, and a second capacitance between the junction point and ground; a drain resistor associated with each individual phase, each drain resistor connected in parallel with the second capacitance for the associated phase; a programmable gain stage associated with each individual phase, each programmable gain stage connected to the junction point for the associated phase; a memory storage connected to each of the programmable gain stages; and a crosstalk cancellation circuit associated with each individual phase, each crosstalk cancellation circuit connected to each of the programmable gain stages for the multi-phase system.
