Abstract :
Demonstrates that low cost, low power sonar signal acquisition systems with dynamic ranges in excess of 120 dB have been routinely produced using hybrid technology. The converters exploit the passive component matching available in hybrid technology and whilst the analogue integrated circuits used are commercially available parts, the digital circuitry needs to be fabricated as a custom ASIC (around 30000 gates complexity).<>
