Automotive, industrial, medical, and many other applications use sensitive analog circuits that must perform their function while remaining immune to noise disturbances in their local environment. Many of these disturbances occur on nearby “noisy” circuits located on the same printed circuit board (PCB), while other interference can be picked up by cable interfaces that couple noise onto the PCB and its circuits.

We are all aware about self-driving cars and all exciting projects the automotive industry is engaged but very few have heard about unmanned ship and projects to operate large fleets of vessels navigating from dock to dock without operational crews (Figure 1).
At early stage but projects such as Maritime Unmanned Navigation Through Intelligence In Networks (MUNIN) investigated feasibility and test-bed development for future developments.
Considering unmanned ships will require extreme reliability from the main generator to single point-of-load, challenges placed on power designers will be far beyond anything we knew.

Medical technology in general is a growth market, regardless of whether this involves devices for use in surgery or intensive care, or in the professional medical environment such as in the laboratory sector or diagnostics. Sales revenue in the USA and Europe was already up by three percent in 2014, with investments in research and development steadily growing by six percent. Firmly on the rise in line with the trend, however, the highest – two-figure – growth figures are in non-imaging diagnostics and in the therapy sector.
