Frequency synthesis for multiband wireless networks
High-speed frequency synthesis is one of the most challenging areas in radio frequency integrated circuit (RFIC) design. It requires a diverse knowledge of both high-speed analog and digital circuits as well as a deep knowledge of system-level issues. The performance requirements on circuits used for frequency synthesis are often extremely demanding making the design of these blocks even more challenging. However, a high-performance frequency synthesizer is a key component in many wired (fiber or cable) and wireless communication systems.
