Abstract:
Today cell phone industry tends to increase the capabilities of the cell phones and at the same time minimize the cost. This trend reflects itself to frequency synthesizer design. Hence, a cheap and efficient way of designing such a frequency synthesizer is suggested in this thesis. The design aims to meet DCS-1800 specifications. The designed frequency synthesizer is based on digital circuits as much as possible. To design such a synthesizer, some different synthesizer and modulation topologies are studied at system level. After deciding on the topology, circuit level design was performed and a full CMOS frequency synthesizer using standard 0.18 μm technology was obtained.
