industrial system reliability in hostile environments. They are exposed to destructive surge voltages, which are caused by ground current spikes from operation transitions of machinery and motor drives, endangering circuit functionality. Employing galvanic isolation is thus imperative to protect the sensor analog front end (AFE) from severe damage. However, the use of an isolation barrier presents several challenges. Without a wired connection to the sensor AFE, power/data must be transferred through the barrier via magnetic or capacitive coupling. Moreover, size and cost are constrained in such applications. In [1], an isolated DC/DC converter is used, which delivers up to 2W with 80% efficiency, but at the cost of bulky external micro-henry transformers. To avoid a large form-factor solution,
