Abstract

We present a nanomechanical parametric amplifier system, which consists of two electrostatically coupled resonators, and operates using 3 frequencies (non-degenerate amplifier). The use of 3 frequencies eliminates phase sensitivity between the signal and pump voltage. We observed the amplification of small signals by up to 43 dB. The width of the response of the resonator is tuned by varying the pump voltage. The resonant frequencies of the individual oscillators can be slightly tuned by adjusting the bias voltages. To our knowledge, this is the first reported mechanical parametric amplification scheme using two separate resonators.
