An Improved Write Driver for Miniaturized Hard Disk Drives

The present work proposes the design of an enhanced driver for magnetic storage write heads to be employed in mini- and micro-drive applications. It is intended for running from a reduced-voltage supply (as commonly found in portable devices) with low power consumption, yet retaining an excellent write speed performance, and is thoroughly programmable. Although originally developed in BiCMOS technology, the design is compatible with a full CMOS process
