摘要:
A recording channel front-end circuit for driving a write element over a transmission line interconnect provides the improved performance during writing of information. In one embodiment, the recording channel front-end circuit includes a voltage-type write driver coupled to the transmission line interconnect and operable to output a write driver signal to the transmission line interconnect and a receiver termination circuit coupling the transmission line interconnect to the write element. The receiver termination circuit may include an impedance matching network operable match a terminal impedance of the write element to be substantially equal to a characteristic impedance of the transmission line interconnect. In another embodiment, the recording channel front-end circuit includes a voltage-type write driver coupled to the transmission line interconnect and operable to output a write driver signal to the transmission line interconnect and a source termination circuit coupling the voltage-type write driver to the transmission line interconnect. The source termination circuit may include an impedance matching circuit operable match a terminal impedance of the voltage-type write driver to be substantially equal to a characteristic impedance of the transmission line interconnect.
