Micromechanical Mixer+Filters
A device comprised of interlinked micromechanical resonators with capacitive mixer transducers has been demonstrated to perform both low-loss frequency translation (i.e. mixing) and highly selective filtering of applied electrical input signals. In particular, successful down-conversion of radio frequency (RF) signals from 40-200MHz and subsequent filtering at a 27MHz intermediate frequency (IF...

متن کاملHigh-Order Micromechanical Electronic Filters
Third-order, micromechanical bandpass filters comprised of three folded-beam resonators coupled by flexural mode springs are demonstrated using an IC-compatible, polysilicon surface-micromachining technology. The use of quarter-wavelength coupling beams attached to resonators at their folding-trusses is shown to suppress passband distortion due to finite-mass nonidealities, which become increas...
متن کاملMicromechanical filters for miniaturized low-power communications
With Q’s in the tens to hundreds of thousands, micromachined vibrating resonators are proposed as IC-compatible tanks for use in the highly selective filters of communications subsystems. To date, bandpass filters consisting of spring-coupled micromechanical resonators have been demonstrated in a frequency range from HF to VHF. In particular, two-resonator micromechanical bandpass filters have ...
متن کاملA Design Methodology for Micromechanical Bandpass Filters
resonators. Higher order means more complexity in design. A third-order high-Q 300 kHz micromechanical bandpass filter, with Q-adjustment and frequency tuning, is analyzed using a parameterized cell library, "NODAS," for schematic representation and behavioral HDL simulation. An equivalent SPICE model of the filter is derived, which enables simulation in SPICE and comparison to NODAS. Frequency...
