Abstract
In the recent years, with the growth of semiconductor process and technology, the wireless communication has been developed more quickly, like IEEE 802.11 series, 3GPP, and Bluetooth technology etc. The Bluetooth Special Interest Group (SIG) was founded in 1998, and they defined Bluetooth as a low cost, low power, short range radio technology.
In this Thesis, we propose a digital IF/Baseband receiver for Bluetooth specification, its data rate is 1 Mb/s, operation clock is 16 MHz, and intermediate frequency is defined as 800 KHz. The I and Q parts of the IF signal after AD converter are the input of our IF/Baseband receiver. In this design, we consider three nonidealities: carrier frequency offset, sampling frequency offset, and additive white Gaussian noise. Since Bluetooth uses a short range radio technology, we do not consider multi-path delay and Doppler effect. We let the IF I and Q signals be influenced by the above three effects, then we use our receiver to demodulate these signals and check whether we can deliver a correct output.
To prove our design, we use Matlab, Verilog, and other CAD tools to run simulations, and then we use FPGA to verify our simulation results. We observe performance factors, like bit error rate (BER) and power consumption, and check whether they conform to the Bluetooth specification or not. Finally, we tape out this chip by using TSMC 0.35μm Mixed Signal (2P4M) CMOS process.
