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.
A shortwave radio, without use of satellites, will receive commercial free foreign government supported English language radio programs from thousands of miles away! Shortwave radios can be built at home in a time period of a few hours to a few weeks. This book contains over one hundred illustrations. Written for both the expert and the novice, it provides information for understanding how the radios work, for obtaining the necessary parts, and for constructing the radios. Shortwave radios were first developed in the 1930s and new designs can be built to resemble radios of that era.
