Abstract: This paper presents the design of low power modulator and demodulator circuits dedicated to a BFSK transceiver, operating in the 863- 870 MHZ ISM band. The two circuits were designed using ams 0.35µm technology with 3V dc voltage supply. Simulation results of the new Direct Digital Frequency Synthesizer in the modulation have shown good performances of the designed system as the Spurious Free Dynamic Range SFDR reached -88 dBc while the circuit consumes only 47.7 µW @ 43.3MHz. The demodulator has also presented a good BER of 10-3 @10.9 EbtoN0 and a sensitivity of about -115 dBm.
