ASICs are increasingly employed in these miniature probes to enhance signal quality and reduce the number of connections needed in mm-diameter catheters [1-5]. 3D visualization in real-time is additionally enabled by 2D transducer arrays with, for each transducer element, a highvoltage (HV) transmit (TX) part, to generate acoustic pulses of sufficient pressure, and a receive (RX) path, to process the resulting echoes. To achieve the required reduction in RX channels, micro-beamforming (μBF), which merges the signals from a subarray using a delay-and-sum operation, has been shown to be an effective solution [3,4].
