COMPARISON WITH VARIOUS MODULATION SCHEMES
PERFORMANCE OF CELLONICS RECEIVER
PROOF OF CONCEPT - DEMONSTRATION ON SYSTEMS
Cellonics allow modem speeds 1,000 times faster than our
The cellonics technology came after studying biological cell
It is based on the way biological cells communicate with each
other and nonlinear dynamical systems (NDS).
Study shows that human cells respond to stimuli and
generate waveforms that consist of continuous train of
pulses separated by periods of silence.
Benefits are incredible speed, simplicity , low power
consumption and robustness.
In current technology , the ASCII uses a combination of ones
and zeros to display a single letter of the alphabet. The data is
sent over radio frequency cycle to its destination where it is
**PRINCIPLE OF CELLONICS
Cellonics stands for electronic cells.
The cellonics element accept an slow analog input waveform
and in return produces predictable fast pulse output thus
encoding digital information and sending it over communication
It has the ability to encode, transmit and decode digital
information over a variety of physical channels, be cables or
wirelessly through the air.
The study of biological cell behaviour is only an
inspiration to the invention of Cellonics circuits. The
Cellonics technology is not related to any neural
network communications or neurophomic electronics.
Slow waveforms: Analog waveforms that vary slowly
with time. These waveforms can be in any arbitrary
Fast waveforms/fast pulse trains: Waveform in the shape of
pulses that varies rapidly with time.
Nonlinear Dynamical Systems (NDS) are the mathematical
formulations required to simulate the cell responses .
Transfer characteristic consists of three different regions.
The two lines at the top and bottom have positive slope 1/RF
and they represent the regions in which the Op-Amp is
operating in the saturated (nonlinear) mode.
The middle segment has a negative slope(Op-Amp operate
slope is positive, the Op-Amp is stable- outputs a
constant saturation voltage.
When slope is negative- the Op-Amp is unstable- the
output is oscillating.
By controlling the duration of the negative slope, the
number of pulses to be produced at the output of
the Op-Amp can be controlled.
THE TRANSFER FUNCTION OF A TUNNEL DIODE EXHIBITS THE “N- CURVE”. BY
CONNECTING AN INDUCTOR AND A TUNNEL DIODE IN SERIES, WE CAN
PRODUCE PULSES THAT ARE SEPARATED BY PERIODS OF SILENCE .
A) BER PERFORMANCE IN A
NARROWBAND COMMUNICATION SYSTEM
The BER performance of the Cellonics modulation is able to
match the theoretical optimal BPSK modulation scheme .
Cellonics receiver will have less implementation losses
B)BER PERFORMANCE IN AN
UWB is a new radio system that occupies an ultra wide
bandwidth and it uses very short impulses of radio energy.
It will cause little interference to the existing spectrum users.
New Life to Communication Devices
Carrier-rate Decoding (i.e. extremely fast decoding rate),
multilevel capability (spectral efficiency), simple circuitry and
Savings on Chip/ PCB Real Estate
Because of its simplicity, a receiver implemented with
Cellonics can save as much as 4 times the chip real estate.
Savings on Power
receiver consumed 3 times less power. This is possible because a
Cellonics circuit is built with a few discrete components that are
mostly passive and hence consume very little or negligible power.
Savings in Implementation Time
In a receiver, the Cellonics™ circuit replaces many traditional
subsystems such as the amplifier, mixer, PLL, oscillator, filter,
crystal quartz, etc. that are necessary in a common Super
Simplicity, low cost, low power consumption of Cellonics™
makes it ideal for use in your next generation of feature-rich
products that need to be small in size and long on power reserve.
