oscillators - Opis:
- Hybrid NEMS interfaces are the key to systems combining the benefits of highly sensitive miniaturized mechanical sensors with the vast functionalities available in electronics. In this context, a phase-locked loop, locking on a suspended resonating carbon nanotube NEMS, is implemented and characterized, able to start, track, amplify and sustain NEMS oscillation up to 100MHz in a sensing environment. Detection of the signals out of the NEMS has been found most challenging and diverse RF front-ends meant for interfacing high-impedance carbon nanotube based NEMS are analyzed. Given the feeble signals from the NEMS, their high output impedance and non-negligible interconnect parasitics, front-end design must imperatively focus on minimal noise figure. Limits on minimal detectable signal are extracted via design, simulation and characterization of a 3-stage common-emitter front-end.
