In this course, the students will be learned the characteristics of MOSFET transistor as a prerequisite of CMOS analog design. The CMOS technology is popular in mixed-signal implementation because it provides density and power saving on digital side and a good mix of components for analog design. The goal of the course is to provide the contemporary concepts about analog CMOS design to meet the demand in mixed signal CMOS Technology. This course involves the topics of MOSFET as amplifier, design specification of single stage amplifier and differential amplifier, current mirror concepts, frequency response and operational amplifiers. Amplification is an essential sub circuit of signal processing systems. The analog signals are amplified because the signal strength is too small to drive the load by overcoming the noise of subsequent stages. The differential amplifier topology is the most important subcircuit which has become the dominant choice of todays high performance analog and mixed signal circuits. The single stage and differential stage amplifier uses the current source. The current mirrors are used for both the purposes i.e. as a biasing element and signal processing component, these are discussed after detailed discussion on differential amplifiers. Operational amplifiers are an integral part of many analog and mixed signal systems. In specific, this course highlights the nonlinearity as an imperfection, which will limit the performance of analog circuits. The trademark of analog design, which is the design challenge to fulfil design matrix, will be highlighted. Students will be guided on design principles to meet design specifications with acceptable accuracy.
