摘要： An ultrasound circuit comprising a trans-impedance amplifier (TIA) with built-in time gain compensation functionality is described. The TIA is coupled to an ultrasonic transducer to amplify an electrical signal generated by the ultrasonic transducer in response to receiving an ultrasound signal. The TIA is, in some cases, followed by further analog and digital processing circuitry.

摘要： An ultrasound device is describe in which analog ultrasonic transducer output signal are directly converted to digital signals. The ultrasound device includes microfabricated ultrasonic transducers directly coupled to a sigma delta analog-to-digital converter in some instances. The direct digital conversion may allow for omission of undesirable analog processing stages in the ultrasound circuitry chain. In some situations, the ADC may be integrated on the same substrate as the ultrasound transducer.

摘要： An ultrasound circuit comprising a multi-stage trans-impedance amplifier (TIA) is described. The TIA is coupled to an ultrasonic transducer to amplify an electrical signal generated by the ultrasonic transducer in response to receiving an ultrasound signal. The TIA may include multiple stages, at least two of which operate with different supply voltages. The TIA may be followed by further processing circuitry configured to filter, amplify, and digitize the signal produced by the TIA.
