This course is concerned with analog integrated circuits for communications with an emphasis on integrated RF circuits. Both theory and circuit design are covered. The course begins with a brief introduction of modern communication systems (both wireless and wireline). It is followed with a review of MOS and bipolar transistor basics. Amplifier circuits are reviewed. A detailed discussion on noise, noise contributors of circuit elements, as well as the analysis of noise in a circuit will be one of the core subjects. Linearity and a general treatment of distortion is presented, and circuit examples are given. Oscillators, and PLLs will be introduced. The course will finalize with a discussion on Mixers, Image Reject Mixers, and Modulators.
