Abstract
A BiCMOS analog front-end to be used in a complete two-chip set with a digital signal processor for compact disc (CD) applications is presented. The proposed device exchanges data with the digital counterpart by means of a I2C-like bus serial interface. Four input signals (currents or voltages) are preamplified with flat group-delay and digitized with 6-bit (for servo path) and 6-bit (for RF path) accuracy. This accuracy is achieved without using an equalizer in the signal path. The system is designed to process CD signal with speed up to 4/spl times/ (i.e. 3.2 MHz bandwidth). The device is realized in a 0.7 /spl mu/m BiCMOS technology using 21.5 mm/sup 2/ chip area.
