Latest Patents

Aravind holds a patent for a "Preamplifier for a writer of a hard disk drive with fast rise time." This invention addresses the high-density storage solutions that require a preamplifier capable of achieving a fast rise time. The quality and speed of the writer are directly influenced by the rise time of the write current waveform. To enhance this rise time, Aravind implemented an improved base driver at the base terminal of an output transistor within an H-bridge amplifier circuit. This innovative base driver features a push-pull driver, a current mirror circuit, and an alternating current coupled signal path. By creating a dip in the voltage at the base terminal during the transition edge of a data signal, the improved base driver increases the base to emitter voltage of the output transistor when it is turning on. This results in a significant boost in the output current driving the writer, thereby reducing the rise time considerably.
