A fully integrated 0.13-μm CMOS mixed-signal SoC for DVD player applications

This paper describes a fully integrated single-chip CMOS mixed-signal system on a chip (SoC) for DVD player applications. It integrates one digital signal processor (DSP), two 32-bit CPUs, three dedicated processing units, a partial response maximum likelihood (PRML) read channel with an analog front end (AFE), and many other subsystems on the same die. The AFE includes a fifth-order G_m-C filter and attains over 66 dB C/N overall. PR(3,4,4,3) structure is employed in the PRML read channel. Owing to the PRML signal processing and the mixed-signal system level optimization in the PRML read channel, less than 10^-6 of bit-error rate (BER) is obtained for the focus offset margins over ±0.5 μm. This SoC is fabricated in 0.13-μm one-poly six-Cu CMOS technology. It contains 24 million transistors in a 63.87 mm² die and consumes 1.5 W at 40 MSample/s data rate, which corresponds to DVD 1.5 times playback operation mode.
