Abstract:

This master thesis describes a radio reciever with simple architecture which operates at 20 MHz. This is based on low-cost amplifier design. Super-Regenerative Receiver (SRR)is re-examined for its simplicity, low-power and short-range wireless applications. Power consumption is kept to a minimal level without any change in the performance of reciever by providing minimum biasing to discrete devices. This report shows how with the help of modern computer based investigation and simulation tools, a much more wide-ranging characterization of the behavior of the reciever is possible.

The Simulation software used to implement this model i advanced Designed System, ADS2006A. This designed model consist of two stages,the linear pre-amplifier stage and the super-regenerative oscillator (non-linear stage). The linear stage has a 1th-order low band-pass filter which connects the input terminal end with the pre-amplifier, while the non-linear stage is consist of class with LC resonant tank, and the self-quenching circuit.

The fundamental quench frequency of this reciever is 8 kHz. In the simulation, the supplied voltage, VDD, is 5,0 volts is used which produced input current of 5,06 mA. The results show that the designed model presents its best performance at the 20 MHz radio frequency (RF).
