Abstract
By the evolution of technology, digital data communication systems have become essential to our daily life. Wireless communication and portable devices become handy and brings the human being with more conveniences. People rely on the usage of portable devices and wireless communication more and more every day. Therefore, this thesis is going to design a low noise amplifier applied on K-band wireless communication. The goal for this design is to achieve small area to meet the demand of portable devices and wireless communication. Quasi-Transformer is utilized in this design to achieve the goal for small area. In the end, we accomplished a design of a low noise amplifier with Quasi-Transformer applied for K-band. This design is tape-out through 0.18μm technology by the Taiwan Semiconductor Manufacturing Company (TSMC). The two stage cascode topology is adopted for the amplifier design to achieve 14dB gain, noise figure of 3.9dB, 15.66mW of power, and occupies 0.506mm2 of area.
