Figure 3: MEMS and Moku:Pro workflow: The Lock-in Amplifier in Slot 2 detects the Feedback signal amplitude A, which is then routed to a PID Controller in Slot 3 to produce the control signal. Subsequently, this control signal is mixed with the phase-locked unit amplitude signal in the Lock-in Amplifier in Slot 4. This process controls the Drive signal’s amplitude to stabilize the amplitude of the resonating mass in the MEMS device. Additionally, Slot 1 hosts an extra Lock-in Amplifier tasked with monitoring the response of the Sensing signal.
