How to Keep a High-Voltage Pulser from Polluting an Ultrasound PCB Receive Path

Ultrasound PCB partitioning becomes difficult when the transmit pulser and the receive AFE share a small probe-side area. During a transmit event, a short high-voltage pulse can create a large local current loop, while the receive channel is trying to preserve a much smaller echo signal. If the board treats those two functions as ordinary...
