Coursera 电子学：放大器 - 基础知识梳理 本课程旨在帮助学生（特别是工程类大学一、二年级学生）扎实掌握放大器的基础知识。通过系统学习，您将轻松透彻地理解晶体管、场效应管等关键概念。 **课程亮点：** * **掌握放大器基础：** 全面理解放大器的基本原理。 * **理想放大器分析：** 深入解析四种理想放大器模型：电压控制电压源 (VCVS)、电压控制电流源 (VCCS)、电流控制电压源 (CCVS) 和电流控制电流源 (CCCS)，并通过实例加深理解。 * **级联效应：** 了解级联技术如何有效提升放大器的放大倍数。 * **参数化分析：** 学习使用 Z 参数、Y 参数、h 参数和 g 参数来描述和分析放大器的输入输出参数关系，并理解任何放大器均可用其中一种参数表示。 * **等效电路：** 通过直观的图形化表示，理解不同参数下的放大器等效电路。 * **通用放大器特性：** 深入探讨电流增益、电压增益、功率增益、输入阻抗和输出阻抗等关键特性，以及它们与 Z、Y 等参数的关系。 * **频率对放大器的影响：** 全面分析频率变化对放大器性能的影响，并按工作频率范围对放大器进行分类。 本课程内容由浅入深，循序渐进，只需跟随从第一讲到最后一讲的学习，即可对放大器这一主题有全面而深入的理解。
Learn the fundamentals of an amplifier. This course will greatly help the students (especially students of first and second year of engineering) to understand transistors, FETs etc. Finally, the course is so designed that if anyone goes from lecture 1 to last lecture the entire subject can be thoroughly understood easily. So let's have a highlight of the entire course quickly-Understand the fundamentals of Amplifiers.Analysis of different types of Ideal amplifiers, i.e. Voltage Controlled Voltage Source (VCVS), Voltage Controlled Current Source (VCCS), Current Controlled Voltage Source (CCVS) and Current Controlled Current Source (CCCS).Understand each type of amplifiers through proper examples.Discussion on Cascading. It is really interesting to know how cascading increases the amplification factor for an amplifier.Analysis of Input output parameter relations of an amplifier by defining Z parameter, Y parameter, h parameter and g parameter. Here, we will learn that every amplifier can be represented by one of these parameters.Equivalent circuits of an amplifier for different parameters. The pictorial representations will be extremely helpful for the students.Properties of a general amplifier i.e. Current gain, Voltage gain, Power gain, Input impedance and output impedance. This is thoroughly discussed through different parameters such as Z parameter, Y parameter etc.The effect of frequency on an amplifier has thoroughly been discussed.Classification of Amplifiers based on range of operation in frequency.
