ABSTRACT:
A quad burst servo demodulator with adjustable slew rate for hard disk drives. The quad burst servo demodulator includes a peak voltage detecting system for detecting the peak voltages of an input signal, a plurality of storage capacitors for holding voltages proportional to the peak voltages observed by the peak voltage detecting system, and a programmable current source for charging (via an adjustable slew rate) the storage capacitors to voltages proportional to the detected peak voltages of the input signal.
