A 1 GHz CMOS analog equalizer for perpendicular magnetic recording

This paper describes the design of a CMOS analog discrete-time equalizer for perpendicular magnetic recording (PMR) read channel. In this design the structure of analog FIR filter that places rotating switch matrix between DAC and multiplier has been proposed. It reduces an accumulative switching er...
