摘要: A disk drive controller including a differential voice coil motor control function is disclosed. The includes an on-chip compensation network for the inner loop, resistor formed of one or more MOS transistors connected in series. gate driven with bias voltage based on tuning current, where current derived so that it varies process and temperature variations integrated circuit, example capacitor. can be tuned sufficient precision to properly compensate loop provide desired frequency response driving drive.
