New RF signal processor IC design for the Mini Disc system

The paper presents a new RF signal processor IC for the MD (Mini Disc) system. The authors have developed an RF signal processor IC with higher performance, smaller size and lower power consumption. This chip contains I/V converters, RF amplifiers, an ALPC (automatic laser power control), an ADIP (address in pregroove) demodulator, a FE low band amp and switch blocks all in one chip.
