    3. 3. **INTRODUCTION** Cellonics allow modem speeds 1,000 times faster than our present modems. The cellonics technology came after studying biological cell behavior. It is based on the way biological cells communicate with each other and nonlinear dynamical systems (NDS).
    4. 4. INTRODUCTION 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.
    5. 5. INTRODUCTION: 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. 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.

    8. 8. LEECH NOCICEPTOR
    9. 9. **SOME CONCEPTS**  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 shape.
    10. 10. .  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 .
    11. 11. **CELLONICS CIRCUITS**
    12. 12. S CURVE TRANSFER CHARACTERISTICS.
    13. 13. , 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).
    14. 14. . 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.
    15. 15. 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 .
    16. 16. ANALOG INPUT --CELLONICS OUTPUT .
    17. 17. COMPARISON WITH VARIOUS MODULATION SCHEMES
    18. 18. **PERFORMANCE OF CELLONICS RECEIVER **
    19. 19. 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
    20. 20. 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.
    21. 21. GSM RECEIVER ARCHITECTURE VS. CELLONICS
    22. 22. **PROOF OF CONCEPT DEMONSTRATION ON SYSTEMS** A: NARROWBAND COMMUNICATION SYSTEM Wireline Cellonics Communication System
    23. 23. B) NARROWBAND COMMUNICATION SYSTEM (WIRELESS)
    24. 24. C. ULTRA WIDEBAND AUDIO SYSTEM
    25. 25. APPLICATION TO TELECOMMUNICATIONS
    26. 26. **CELLONICS ADVANTAGES** New Life to Communication Devices Carrier-rate Decoding (i.e. extremely fast decoding rate), multilevel capability (spectral efficiency), simple circuitry 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.
    27. 27. 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.
    28. 28. CONCUSION 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.
