Query: A System for Generating Non-Uniform Random Variates using Graphene
  Field-Effect Transistors   We introduce a new method for hardware non-uniform random number generation
based on the transfer characteristics of graphene field-effect transistors
(GFETs) which requires as few as two transistors and a resistor (or
transimpedance amplifier). The method could be integrated into a custom
computing system to provide samples from arbitrary univariate distributions. We
also demonstrate the use of wavelet decomposition of the target distribution to
determine GFET bias voltages in a multi-GFET array.
  We implement the method by fabricating multiple GFETs and experimentally
validating that their transfer characteristics exhibit the nonlinearity on
which our method depends. We use the characterization data in simulations of a
proposed architecture for generating samples from dynamically-selectable
non-uniform probability distributions.
  Using a combination of experimental measurements of GFETs under a range of
biasing conditions and simulation of the GFET-based non-uniform random variate
generator architecture, we demonstrate a speedup of Monte Carlo integration by
a factor of up to 2$\times$. This speedup assumes the analog-to-digital
converters reading the outputs from the circuit can produce samples in the same
amount of time that it takes to perform memory accesses.
