Abstract
A first CMOS analog front-end processor for a 4X speed CD-ROM is designed and fabricated in a 0.8μm process. The IC consists of RF amplifiers, an asymmetry compensation circuit, an automatic power control circuit for laser diode, a bandgap reference, and a servo control signal generator which includes track and focus error detecting circuits, and a defect detecting circuit. The circuit enables to design a true one chip 4X speed and 8X speed CD-ROM in digital domain.
