The embodiments described herein provide systems and methods for determining the health status of a sensed switch. In general, the embodiments described herein determine a measure of a health status of the sensed switch by comparing a voltage on the sensed switch, ascertaining a first comparator state under one test condition and ascertaining a second comparator state under a second test condition. The first comparator state and the second comparator state are and then compared to determine the measure of the health status of the sensed switch.

Techniques are described herein to enhance capability of floating level translators. For example, increased headroom is accomplished by adaptively bypassing the protection elements of the voltage level translator. In an example, a floating level translator can translate an input signal from a low-voltage domain to a high-voltage domain. A bypass circuit is coupled across the protection elements. The bypass circuit selectively engages during low-voltage operation (e.g., thereby providing a lower loss path relative to loss caused by the high-voltage protection elements and thus increasing the headroom swing), and disengages responsive to the high-voltage reference rail of the high-voltage domain exceeding a threshold or otherwise being high enough (e.g., greater than the potential of the low-voltage domain power rail). The bypass circuit can be implemented in a relatively low-complexity manner (e.g., back-to-back high-voltage FETs) without additional signals to control low-voltage capability.

A sensor such as an accelerometer includes a proof mass located opposite a plurality of electrodes located on a substrate. Some of the electrodes are auxiliary electrodes that apply an alternating current auxiliary signal to the proof mass while other electrodes are sense electrodes that sense movement of the proof mass. When a residual voltage is not present on the proof mass or on the sense electrodes, the forces imparted by the auxiliary signal onto the proof mass are substantially balanced. When the residual voltage is present on the proof masses, forces at a first harmonic frequency of the auxiliary signal are sensed by a sense electrode of the sensor. A self-test is failed if the sensed forces exceed a threshold.
