Frequency stability of graphene nonlinear resonators

Introduction

These files contain code on three topics:

  1. Calculate the Allan Deviation with more control about the number of points calculated.

  2. Parse stream files from the Zurich Instruments UHF into .mat files, one per signal.

  3. Model and configuration files for the simulations.

Allan Deviation

The file is located in the root of this structure and called allandev.m. The comments contain the information required to run it.

UHFLIStreamParser

This directory contains a set of files to parse stream files into .mat files per signal.

Main file is UHFLIStreamParser.m. The other files are helpers for this function or wrappers to select a batch of stream files to parse.

Simulation

The simulation directory contains the Simulink model used in the master thesis: PLL_duffing_with_thermal_noise_nonlinear_damping.slx.

To run this, one needs to load parameters for the system. A start can be found in graphene_drum_parameters.m.

A phase sweep can be executed by running run_nonlinear_damping_experiments_in_simulations.m.

The other files in this directory are helper functions.
