Abstract: A passband filter includes a first and second microelectromechanical resonator system, each including a resonating beam, a drive electrode, and a sense electrode. An AC input signal is coupled to the drive electrode of the first and second microelectromechanical resonator system. A differential-to-single ended amplifier has a first input and second input respectively coupled to the sense electrodes of the first and second microelectromechanical resonator systems. An output of the differential-to-single ended amplifier is an output of the passband filter that provides a bandpass filtered signal of the AC input signal. A DC bias signal is coupled to the resonating beams of the first and second microelectromechanical resonator systems. The first microelectromechanical resonator system exhibits a hardening nonlinear behavior defining an upper stop frequency of the passband and the second microelectromechanical resonator system exhibits a softening nonlinear behavior defining a lower stop frequency of the passband.

Abstract: A mechanical resonator-based cascadable logic device includes which includes a resonator having a beam with a first fixed end, a second fixed end, and a length between the first and second fixed ends. A first electrode and a second electrode are aligned along a first side of the beam. A third electrode and a fourth electrode are aligned along a second side of the beam and opposite the first and second electrodes. A DC voltage source is coupled to one of the first and second fixed ends of the beam. At least one of the first, second, third, and fourth electrodes is coupled to a first AC voltage source so that a logic operation is performed by activating a second resonant mode of the resonator.
