WebMEMS are being developed for use at harsh conditions. In harsh-environment and high-performance (e.g., military) guidance applications inertial sensors must be sensitive to low rates of rotation yet survive the high blast loads associated with the initial launch. In this multi-year study, a set of tuning fork gyroscopes were subjected to a ... Webthe system is differential. Observing the circuit, we can see the Mems Capacitors (C+dC and C-dC) and a reference capacitor (C4 and C5). We can calculate the output voltage Vo of the two branches separately, and then of the entire circuit. Figure 4 - Electric model of the MEMS Capacitive Accelerometer We have vmp (vm+) and vmn (vm-).
