Download or read book An 8 PSK Super Regenerative Receiver written by Sanjay Subbarao and published by . This book was released on 2015 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: 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 Quadrature Phase Shift Keying and 8-Phase Shift Keying.

This book was released on 2017 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Super Regenerative Receivers exploit more complex modulation techniques in order to achieve better bit per symbol rate. This study presents a novel 8-Phase Shift Keying (PSK) Super Regenerative Receiver operating in the 402--405 MHz, Medical Implant Communication Service (MICS) band. In the proposed architecture, the complexity of the circuit input is reduced by using an enable signal, which produces a quenching current source in the Low Noise Amplifier (LNA) and Super Regenerative Oscillator (SRO) circuit. Furthermore, the receiver uses a new RC-CR network to generate eight equally shifted signals and one Flip-Flop in each path to minimize the amplitude mismatch and the number of components, respectively. This receiver has been designed and simulated in 130 nm Complementary Metal Oxide Semiconductor (CMOS) process. The power consumption of the entire receiver is 119 μW for the input signal of -80 dBm, at the rate of 6 Mbps, and the Energy Per Bit of 19.8 pj/b.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Radio Frequency (RF) communication has developed tremendously over the past two decades. Short-range wireless applications, such as sensor networks, robotics, and home automation, require small area and low power consumption. The receiver must be designed in such a way that it optimizes the area with simple circuitry and minimizes its turn on time to achieve these requirements. This project focuses on designing the 16-PSK (Phase Shift Keying) super regenerative receiver to achieve digital transmission at a higher data rate with low power consumption. The receiver is designed with a Low Noise Amplifier (LNA), Super Regenerative Oscillator (SRO), buffers, RC networks, latches, and flip-flops. The receiver is designed at the 400 MHz frequency with 130nm Complementary Metal Oxide Semiconductor (CMOS) process technology. This receiver can correctly detect the -80 dBm, 4-Mbps signal with a power consumption of 164 [mu]W and Energy Per Bit (EPB) of 0.041nj/b.
