    • 3. **INTRODUCTION**  Cellonics allow modem speeds 1,000 times faster than our present modems.  It is based on the way biological cells communicate with each other and nonlinear dynamical systems (NDS).  Benefits are incredible speed, simplicity, and robustness.
    • 4. INTRODUCTION 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 of silence.
    • 5. INTRODUCTION: 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 then decoded.
    • 6. **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 air.
    • 7. MEASURED ß-CELL RESPONSE
    • 8. LEECH NOCICEPTOR
    • 9. ANALOG INPUT --CELLONICS OUTPUT
    • 10. **SOME CONCEPTS** 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 algorithms. 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.
    • 11. . 4) Nonlinear Dynamical Systems (NDS) are the mathematical formulations required to simulate the cell responses .
    • 12. **CELLONICS CIRCUITS**
    • 13. S CURVE TRANSFER CHARACTERISTICS.
    • 14. , 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 linearly).
    • 15. dVs/dt = (V) depending on the slope of the triangular input waveform. 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.
    • 16. 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 OF SILENCE.
    • 17. **PERFORMANCE OF CELLONICS RECEIVER **
    • 18. 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 losses
    • 19. B)BER PERFORMANCE IN AN ULTRA WIDEBAND  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.
    • 20. 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
    • 21. **PROOF OF CONCEPT DEMONSTRATION ON SYSTEMS** A: NARROWBAND COMMUNICATION SYSTEM Wireline Cellonics Communication System
    • 22. 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 .
    • 23. B) NARROWBAND COMMUNICATION SYSTEM (WIRELESS)
    • 24. NARROWBAND COMMUNICATION SYSTEM (WIRELESS) Transmitter and receiver comprise of three modules: 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.
    • 25. C. ULTRA WIDEBAND AUDIO SYSTEM
    • 26. 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 .
    • 27. APPLICATION TO TELECOMMUNICATIONS
    • 28. **CELLONICS ADVANTAGES** 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.
    • 29. CELLONICS ADVANTAGES  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 design.
    • 30. CELLONICS ADVANTAGES  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
    • 31. COMPARISON WITH VARIOUS MODULATION SCHEMES
    • 32. CONCUSION  The Cellonics communication method is one inspired by how biological cells signal.  With the Cellonics method, noise-generating and power-consuming systems such as voltage-controlled oscillators, PLLs, mixers, power amplifiers, etc., are eliminated.
