ABSTRACT:
A distributed delta-sigma analog-to-digital (A/D) converter is partitioned between an ultrasonic probe and an imaging console which are coupled to each other by optical links. The ultrasonic probe houses an integrator for receiving an analog input signal and generating an integrated analog output signal. The integrated output signal is supplied to a light emitting diode for generating a light beam. The probe also houses photoconductive switches for coupling positive and negative reference voltages to a summing node of the integrator. The imaging console houses a photodiode for receiving the light beam via a fiber optic cable and converting the light beam to an analog electrical signal which is later converted to a digital signal. A feedback loop includes an internal A/D converter in the console that is coupled to the photoconductive switches via LED-generated light beams passed through other fiber optic cabling.
