  • High-speed write driver
    Patent number: 7151393
    Abstract: A write driver includes two field-effect/bipolar transistors with feedbacks between the drains/collectors and gates/bases, a write/read switch connected between the drains/collectors and a positive power supply, an impedance matching circuit connected to the drains/collectors to match both differential and common mode output impedance of the write driver to an input impedance of a flex circuit, a common mode output voltage control circuit coupled to the transistors, and a differential mode output voltage control circuit coupled to the transistors.
    Type: Grant
