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.在此所述的技術特點係有關於超音波設備，其係包含直接電耦接至三角積分的類比至數位轉換器(ADC)的電容式微加工超音波換能器(CMUT)。該設備在每一個CMUT以及三角積分ADC之間可以並無放大器或是多工器。該設備可包含在100到20,000個之間的CMUT以及在100到20,000個之間的三角積分ADC，該些CMUT的每一個係直接電耦接至該些三角積分ADC中之一。該些CMUT以及該些三角積分ADC可以被單體整合在單一基板上。該些三角積分ADC可以並無與該CMUT有區別的積分器。該CMUT的一內部的電容可以作為一用於該三角積分ADC的積分器。
