Abstract

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, we analyze diverse RF front-ends meant for interfacing high-impedance carbon nanotube based NEMS. 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.
