Abstract
A system including a magnetic coil and a coil driver is described. The magnetic coil has a parasitic capacitance. The coil driver is coupled with the magnetic coil. The coil driver includes a pulse generator and a switching module coupled with the pulse generator. The pulse generator provides a pulse train. The switching module receives the pulse train and provides a switched driving signal to the magnetic coil. The switched driving signal has a frequency not less than a parasitic capacitance frequency.
