Wireless apparatus IC design for motor-engine rotate speed measurement

In this paper, the operation theory and the signal processes of the motor-engine rotate speed wireless measure apparatus are introduced. Because the most parts of its circuits are digital circuit, the process of its integration on a single chip is discussed in this paper. The hardware language VHDL is used in designing the circuit of the digital part, and the software Foundation of Xilinx Company is used to have a simulation and synthesis for the design. The design is verified by a FPGA experiment.
