The Design of Analog Front-End Circuitry for 1X HD-DVD PRML Read Channel

In this paper, the design techniques and considerations for each building block required for analog signal processing in HD-DVD PRML read channel are presented and the procedures of analog signal processing are also described. The Analog Front-End Circuitry (AFE) includes the circuits of RF Summer Attenuator Equalizer AGC and ADC. The Equalizer is constructed by seven-pole two-zero 0.05 degree equiripple linear phase Gm-C filter. It has a cutoff frequency (fc) tunable between 8 and 39MHz and it is also able to provide up to 12dB of boost at fc. The constant group delay
