Abstract: Aspects of technology described herein relate to ultrasound apparatuses including capacitive micromachines ultrasonic transducers (CMUTs) that are directly electrically coupled to delta-sigma analog-to-digital converters (ADCs). The apparatus may lack an amplifier or multiplexer between each CMUT and delta-sigma ADC. The apparatus may include between 100 and 20,000 CMUTs and between 100 and 20,000 delta-sigma ADCs, each of the CMUTs directly electrically coupled to one of the delta-sigma ADCs. The CMUTs and the delta-sigma ADCs may be monolithically integrated on a single substrate. The delta-sigma ADCs may lack an integrator distinct from the CMUT. An internal capacitance of the CMUT may serve as an integrator for the delta-sigma ADC.
