This study presents an analysis of different analog front-end architectures for such imaging, in particular their impact on the signal-to-noise ratio (SNR). The focus is on systems with high pulse repetition frequencies (PRF) and sampling rates of up to 50 Mega-Samples per second (MSPS). The architectures, which is tailored to Piezoelectric and Capacitive Micromachined Ultrasonic Transducer (PMUTs & CMUTs), include combinations of analog front-ends (AFE), preamplifiers, transimpedance amplifiers, and analog-to-digital converters (ADC). For testing purposes, the MUTs are simulated and set up with passive components.enReadoutSignal conditioningDigitalizationAnalog front-endPhotoacoustic imagingconference paper
