#### Course Goals

The goals of this course are as follows: Students will become familiar with the principles of non-linear circuit design, and sufficiently skilled at analysis of such circuits that they are prepared for advanced courses on integrated circuit design. Students will be able to differentiate between analog (linear) and digital circuits. For a given circuit configuration and DC bias, the students will be able to define gain, input/output resistance, and frequency response. Students will be aware of the non-ideal characteristics of bipolar and MOS transistors, and able to make design trade-offs to achieve a set of conflicting goals.
