Abstract :
A model of GFSK (Gaussian Frequency Shift Keying) signal demodulator that makes use of time to digital conversion is presented. It has been implemented in the Simulink environment. The performance of the demodulator is investigated for various values of design parameters. Process variations, delay line length, delay cell jitter and delay value are modeled and analyzed. The proposed model can be used to set requirements for the electrical design that lead to satisfying Bluetooth BER (Bit Error Rate) required performance (0.1%) in the optimal way.
