Custom design of CMOS low-power high-performance digital signal-processing macro for hard-disk-drive applications

The design challenges and custom design techniques associated with low-power, small-area, high-performance CMOS digital signal-processing circuits for hard-disk-drive applications are presented. The advantages of custom design are demonstrated by an example custom digital FIR filter macro that provides substantial improvement in performance, area, and power dissipation over standard-cell implementations.
