Inertial imaging using mechanical resonators allows for estimation of the mass distribution (and its spatial moments) of physical adsorbates on the resonator surface by tracking the frequency shift associated with multiple normal modes. Increased ima

This paper describes the operation of weakly coupled resonators in the nonlinear domain in a closed loop configuration. The amplitude-frequency curves are mapped for both the resonators in the unstable regime to identify the two bifurcation points. T

In this paper, we present an analog high-precision temperature controller designed to stabilize the temperature of MEMS inertial sensors with a short-term stability of better than $\pm 50 \ \mu^{\circ}\mathbf{K}$ and long-term stability of $\pm 250\

In this paper, we present a resonant MEMS accelerometer (RXL) using AC polarization voltage as an alternative to the existing DC polarization schemes. By making full use of the intrinsic frequency mixing property of a parallel plate capacitive transd

Micromechanical resonators present versatile platforms for probing nonlinear dynamics. One such recent illustration is the experimental observation of ‘phononic frequency combs’. Using an exemplar resonator device, this paper probes the emergence

This paper presents a new class of oscillator topology requiring only one constant gain transimpedance amplifier in the loop. An amplitude control is realized through the amplitude modulation effect within a coupled resonator system. Control of the o
