Analogue array solves DVD performance
problems
The Conradt Measurement and Control development company has designed an innovative analogue lens control solution which dramatically improves the write speed of DVD peripherals.
The Conradt Measurement and Control development company has designed an innovative lens control solution which dramatically improves the write speed of DVD peripherals - and their resistance to vibration - by implementing the control loops using analogue technology in place of established digital, DSP-based approaches Based on an Anadigm AN10E40 field-programmable analogue array (FPAA), the design provides a cost-effective means of increasing control loop performance way beyond the levels offered by today's DVD pick-up designs

Software puts standard filters on analogue arrays
Anadigm has added filter synthesis to its field-programmable analogue array (FPAA) configuration software.
It avoids expensive increases in the performance of digital control circuitry, while simultaneously overcoming problems of pick-up oscillation that DVD manufacturers face as write speeds increase.
Analogue-based control was chosen over digital because the target increases in control speeds would have required prohibitively-expensive high resolution A/D conversion, along with increases in DSP speed.
