A new super-regenerative transceiver for use in low power binary frequency shift keying (BFSK) digital communication systems is presented. The classic on/off keying (OOK) design is reviewed and motivation to extend the design to BFSK is given. The system is shown to preserve the low power qualities of the classic super-regenerative transceiver while obtaining the increased speed and reliability of BFSK modulation. Operation of the new system is explained at the system level and insight into the circuit design is also given. Simulations show the transceiver allows transmission rates on the order of 250kbps with a link power of less than 1.4mW.
