Abstract

A current-driver write driver for a +5/-5 V preamplifier is described in this paper. This IC, which incorporates RC load for harmonic oscillation to enlarge the voltage swing across the head and Super Push-Pull Logic (SPL), drives the write driver with a good rise/fall time. This write driver, built with a 0.35 /spl mu/m SOI-BiCMOS process, has demonstrated a rise-time as short as 0.45 ns with a 160 mA peak-to-peak output write current.

用于硬盘驱动器的SOI-BiCMOS 800mbps写入驱动程序

介绍了一种用于+5/-5 V前置放大器的电流驱动写驱动。该IC集成了RC负载的谐波振荡，以扩大整个磁头的电压摆动和超级推挽逻辑(SPL)，以良好的上升/下降时间驱动写驱动器。该写入驱动器采用0.35 /spl mu/m SOI-BiCMOS工艺，其峰值输出写入电流为160 mA，上升时间短至0.45 ns。
