Picking up where we left off in Part 1, we need to explore some methods to mitigate problems caused by unpredictable ground currents. Let’s start with some simplification, although we may need to first complicate things to then simplify them. First, let’s arrange a massive ground plane around the analog circuitry on the PC board.

Minimizing electrical noise to improve medical-ultrasound images, Part 3
Low-noise circuitry is critical to image quality of medical ultrasound, an indispensable diagnostic tool. Efficiency versus noise It may seem that if there is a tradeoff between power-supply noise versus potential efficiency, the need for ultralow noise in the ultrasound application should prevail. After all, a few more tens of milliwatts of dissipation should not […]
Minimizing electrical noise to improve medical-ultrasound images, Part 2
Low-noise circuitry is critical to image quality of medical ultrasound; an indispensable diagnostic tool. Despite the conceptual simplicity of the underlying principle, a complete, high-end ultrasound imaging system is a complicated device (Figure 1). The ultimate performance of the system is largely determined by the transducer and analog front end (AFE), while post-processing of the […]
