A CMOS analog front-end processor for a 4X speed CD-ROM is designed and fabricated in a 0.8-μm process. The IC consists of RF amplifiers, pulse reshaping circuits, an automatic power control circuit for laser diode, and a servo control signal generator which includes track and focus error detecting circuits. Experimental result shows that its RF performance is enough for 8X speed CD-ROM. The circuit enables to design a true one chip 4X speed and 8X speed CD-ROM or DVD player in digital CMOS process technology.
