Title: Electrical time constant compensation method for switched, voltage-mode driver circuit
Inventor: HILL JOHN P
IPC: G11B5/596
Filed: 2002-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a system and a method which make it possible to correct a driver at a faster rate. SOLUTION: A power driver for driving a signal on a load uses a voltage- mode driver. A system processor generates commands indicating a programmed drive signal desired from the voltage-mode driver. A lead compensator determines a compensated command to compensate for an admittance function of the load. The compensated commands are coupled to the voltage-mode driver, so that the voltage-mode driver generates a voltage output based upon the compensated command.
