PRINCIPLE OF CELLONICS TECHNOLOGY
PERFORMANCE OF CELLONICS RECEIVER
PROOF OF CONCEPT - DEMONSTRATION ON SYSTEMS
COMPARISON WITH VARIOUS MODULATION SCHEMES
Cellonics allow modem speeds 1,000 times faster than our present
It is based on the way biological cells communicate with each other and
nonlinear dynamical systems (NDS).
Benefits are incredible speed, simplicity, and robustness.
The cellonics technology came after studying
biological cell behavior.
Study shows that human cells respond to stimuli
and generate waveforms that consist of
continuous train of pulses separated by periods
It consume very little power.
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 TECHNOLOGY
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 channel.
It has the ability to encode, transmit and decode digital information
over a variety of physical channels, be cables or wirelessly through
The cellonics technology is a fundamental modulation and
demodulation technique. The Cellonics receivers generate
pulses from the received analog signal and perform
demodulation based on pulse counting and related
1. 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.
2. Slow waveforms: Analog waveforms that vary slowly
with time. These waveforms can be in any arbitrary shape.
3. Fast waveforms/fast pulse trains: Waveform in the
shape of pulses that varies rapidly with time.
4) Nonlinear Dynamical Systems (NDS) are the mathematical formulations required
to simulate the cell responses .
Transfer characteristic consists of three different
The two lines at the top and bottom have positive
1/RF and they represent the regions in which the
Op-Amp is operating in the saturated (nonlinear)
The middle segment has a negative slope(Op-Amp
dVs/dt = (V) depending on the slope of the triangular
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, he
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 “NCURVE”. BY CONNECTING AN INDUCTOR AND A TUNNEL DIODE IN
SERIES, WE CAN PRODUCE PULSES THAT ARE SEPARATED BY PERIODS
A) BER PERFORMANCE IN A
NARROWBAND COMMUNICATION SYSTEM
The BE performance of the Cellonics modulation is
able to match the theoretical optimal BPSK
modulation scheme .
Cellonics receiver will have less implementation
B)BER PERFORMANCE IN AN ULTRA
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.
GSM RECEIVER ARCHITECTURE VS. CELLONICS
Drawback of superheterodyne: Device noise inter modulation, local oscillators/mixer isolation, Phase Lock Loop (PLL) switching
time and noise immunity
Consumption of considerable amount of power
**PROOF OF CONCEPT DEMONSTRATION ON SYSTEMS**
A: NARROWBAND COMMUNICATION SYSTEM
NARROWBAND COMMUNICATION SYSTEM
In this system, a CD-ROM player is used as a convenient
signal source to provide the required bit stream. The digital
data is modulated using a pulse width modulation scheme.
These modulated data are then passed through a700-ft
telephone wire line. At the receiver, the data is demodulated
using the “N-shaped” Cellonics circuit, which uses only two
elements - an inductor in series with a tunnel diode. To
recover the digital information, the decision device simply
counts the pulses to determine if it is a logic ‘1’ or ‘0’. The
recovered data is then output to an audio player for real .
Transmitter and receiver comprise of three
1.The PC/DSP module :provides a high-speed data
transmission interface with the transmit/receive PC .
2.Base band transceiver module: converts these
data from the DSP into FSK-like waveforms.
3.The RF transmit/receive module:down converts
the received signal using an AM envelope detector.
ULTRA WIDEBAND AUDIO SYSTEM
This system demonstrates the live transmission of
compact disc music using UWB wireless technology.
Digital data from two CD-ROM players is tapped at a
rate of 11.4 Mbps. This data stream is fed into a
UWB pulse generator and transmitted wirelessly. At
the receiver end, the signal is detected and then fed
to a Cellonics receiver to decode and the original
music data is recovered/sent to an audio player for
real-time playback .
New Life to Communication Devices
Carrier-rate Decoding (i.e. extremely fast decoding rate),
multilevel capability (spectral efficiency), simple circuitry, low
power consumption and low cost.
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 heterodyne and Super homodyne
Build or Rejuvenate your Products with Cellonics
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
The Cellonics communication method is one inspired by how biological
With the Cellonics method, noise-generating and power-consuming
systems such as voltage-controlled oscillators, PLLs, mixers, power
amplifiers, etc., are eliminated.
