Abstract :
A fully analog approach to an adaptive equalizer is designed in 1.0 μm 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
