ABSTRACT:
The present invention achieves technical advantages as an improved Parallel Damping scheme suitable for very-low-supply preamp operation. The improved Parallel Damping Scheme accurately generates a programmable Iw flowing through the write head while compensating for a leakage current path through a Parallel Damping resistor.
