This lecture will provide some course information such as the main objective, general topics to be covered, grading policy, and syllabus. Also, a brief history of micrelectronics will be introduced together with the fundamental knowledge related to this class.
In this lecture, we will start from some examples for electronic systems in our daily live. The concept of analog vs. digital signal will be explained in details. Also, the basic and very imporant circuit theorems including KVL, KCL, Thevenin, and Norton are discussed.
This lecture will introduce the operating principles for semiconductor, including the concept of free carriers, bandgap, and doping in semiconductor. The 2nd part of this lectures will explain the carrier transport mechanisms in semiconductors. The details of drift and diffusion current will be discussed.
In this lecture, we will talk about the PN junction (diode) based on the semiconductor materialts, which is the basis for more advaced semidoctor devices such as BJT and MOSFET. Detailed analysis will be shown based on different bias conditions of the diode. The I-V characterists and equivalent circuit models are also discussed.
Based on the diode models discussed in lecture 4, we will talk about some circuits using diodes. The transfer function of the circuits is discussed. A very important concept of using the small-signal model to simplify the circuit analysis is introduced. The circuits using diodes such as rectifiers and limiters will also be discussed in this lecture.
In this lecture, the transistor structure and physics will be introduced first, followed by the I-V characteristic of BJT. Also, the equivalent-circuit model including this small-signal and large-signal will be discussed.
In this lecture, the MOS device structure and physics will be introduced first, followed by the I-V characteristic of MOSFET. The equations of drain current and transconductance will be derived. Also, the equivalent-circuit models under the and large-signal operation will be discussed.
In this lecture, the general design considerations and biasing of a single-stage amplifier will be discussed including the input/output impedance, different amplifier topologies, and DC/small-signal analysis. Also, different biasing configurations will be introduced such as the resitive divider and self-bias topologies.
This lecture will discuss the CE and CS single-stage amplifiers. The concept of load-line will be introduced to determine the optimal bias point. Also, the impact of emitter degeneration on gain and input/output impedances will be shown. The current-souce and diode-connected loads will be discussed in the end.
This lecture will discuss the CB and CG single-stage amplifiers. The reason of using these two topologies in practical applications will be explained. Also, the impact of the emitter/source resistance on gain and input/output impedances will be shown. The bias scheme for the CB and CG configurations will also be discussed.
This lecture will discuss the CC and CD single-stage amplifiers. The reason of using these two topologies in practical applications will be explained. The small-signal gain and input/output impedance will be calculated with the emitter/source biased by a resistor or a current sourece. The bias scheme for the CC and CD configurations will also be discussed. Finally, a two-stage amplifier using the emitter follower as the output stage will be discussed.
In this lecture, the general consideratons of transfer fuction and frequency response will be discussed in details. The Bode plot will be illustrated by the single time constant (STC) network first to describe the frequency response. The frequency reponse of amplifers will be analyzed based on the STC networks. The Miller's theorm and high frequency transistor model will also be introduced.
In this lecture, the frequency response for differnet circuit topologies will be discussed including CE(CS), CB(CG), and the emitter (source) follower. The open-circuit time constant technique will be used to determine the frequency response characteristics of the amplifiers.
In this lecture, the cascode stage will be discussed, which is very useful for both amplifier and current source applications. The gain, output resistance, and frequency response of cascade topology will be derived. The current mirror for IC biasing will be introduced and the applications for circuit design will be discussed.
In this lecture, the differential amplifier will be introduced. The advantages of using the differential pair for IC design will be explained. The small-signal analysis of differential pair will be discussed, followed by the concept of the half circuit. The differential pair with the active current mirror load and the frequency response will be shown at the end.
