Abstract

The proposed demodulator is an all-digital implementation of a FM demodulator. The proposed design intends to implement a FM demodulator for high-speed applications, which makes the requirements for analog components minimal. The proposed circuit is an all-digital quadrature demodulator, where the individual components have been implemented without using any multipliers. The topology uses a Pulse width modulation (PWM) block to avoid the need for a DAC.

The Xilinx virtex-7 FPGA has been used as the reference device for the work. The circuit is validated through behavioral simulations and the results conclude the proposed circuit demodulates the targeted FM channel and provides the spectrum information for the targeted FM channel
