Abstract
A transformer is configured to receive an input electrical signal at input nodes and supply an output electrical signal at output nodes. The transformer includes windings wound on the core between the input and output nodes. The windings define a signal path to transform the input electrical signal into the output electrical signal along the signal path. The transformer includes a first insulated conductive layer arranged between first and second windings configured to receive a first bias voltage. The transformer includes a second insulated conductive layer arranged spatially proximate to the first and second windings configured to receive a second bias voltage. The first and second insulated conductive layers form an electrostatic field that is based on a potential difference between the first and second bias voltages independent of the signal path. The windings are arranged to be within the formed electrostatic field.
