J.S. Ienowski; Rajeev Badyal; Andrew Brown; Charles E. Moore; Rob Morling; Thomas M. Walley; Christopher Huw Williams; David J. Allstot; Hugh Wallace

A fully analog approach to an adaptive equalizer is designed in 1.0 /spl mu/m CMOS. The 13 tap FIR filter is a key component of a PRML read/write channel mixed signal IC for digital audio tape (DAT) format tape drives. A variety of continuous time, current mode, switched capacitor, and offset cancellation techniques are used to achieve desired performance.
