A voltage compensation unit reduces the effects of induced voltages upon a
device having a single wire line. The single wire line has balanced
characteristic impedance. The voltage compensation unit includes a
tunable compensation circuit connected to the wire line. The tunable
compensation circuit applies supplemental impedance to the wire line. The
supplemental impedance causes the characteristic impedance of the wire
line to become unbalanced, thereby reducing the effects of induced
voltages caused by changing magnetic fields.
