The Super-Regenerative Reception concept was developed in the early 1900s. The evolution of Heterodyne Reception has forced it into oblivion. However, recent research and development has emphasized its use in short distance and low power wireless applications. The results indicate extremely low power and high gain with small circuit area. The study herein focuses on a receiver using a Super Regenerative Oscillator to decrypt 8-PSK Signals. Demodulation without the use of a Local Oscillator, a Phase Locked Loop or an Analog to Digital Converter is proposed. The architecture of encoding is prese...
The Super-Regenerative Reception concept was developed in the early 1900s. The evolution of Heterodyne Reception has forced it into oblivion. However, recent research and development has emphasized its use in short distance and low power wireless applications. The results indicate extremely low power and high gain with small circuit area. The study herein focuses on a receiver using a Super Regenerative Oscillator to decrypt 8-PSK Signals. Demodulation without the use of a Local Oscillator, a Phase Locked Loop or an Analog to Digital Converter is proposed. The architecture of encoding is presented which is in turn used to generate the necessary input at the receiver. The receiver involves a combined Low Noise Amplifier Super- Regenerative Oscillator architecture in a single stack configuration for the feature of current reuse. Simulation results are presented which confirm the theory. Finally, a comparative study is presented for various modulation techniques including QuadraturePhase Shift Keying and 8-Phase Shift Keying.
