A re-configurable ADC for acoustic phased arrays

A re-configurable analogue to digital converter (ADC) for underwater acoustic phased array transducers was developed and tested in this study. The ADC achieved a 7.18 effective number of bits resolution with a sampling frequency of 10 MHz. It was implemented in a field programmable gate array (FPGA). The proposed method interfaces an array transducer directly with the FPGA using minimal external components and could be fine-tuned for a specific instrument type.
