Topic outline

  • in this section we study basic amplifier definitions such as gain and stability in real transistor amplifiers. To prepare for lesson and homework assignment read and study sections 11.1-11.3 in the 3rd edition, or sections 12.1-12.3 in the 4th edition of the course book. There are a lot of mathematical derivations that you do not need to memorize. The main point is to grasp what this all means in practice! Hence, pay attention mainly to the definition of transducer power gain, the role of unilaterality and unconditional stability (or potential instability) in real transistor amplifiers, as well as the use of constant-gain circles and constant-noise figure circles in the amplifier design process.
