TOPIC (UNIT) TITLE Unit 1: Characteristics of MOS Transistors
DESCRIPTION
The MOS Field Effect Transistor (MOSFET) is the fundamental building block of MOS and CMOS digitalintegrated circuits. Compared to the bipolar junction transistor (BJT), the MOS transistor occupies arelatively smaller silicon area, and its fabrication involves fewer processing steps. These technologicaladvantages, together with the relative simplicity of MOSFET operation, have helped make the MOStransistor the most widely used switching device in LSI and VLSI circuits. In this unit, we will examine thebasic structure and the electrical behaviour of nMOS (n-channel MOS), as well as pMOS (p- channel MOS)devices. The nMOS transistor is used as the primary switching device in virtually all digital circuitapplications, whereas the pMOS transistor is used mostly in conjunction with the nMOS device in CMOScircuits. However, the basic operation principles of both nMOS and pMOS transistors are very similar toeach other.
DETAILED COURSE TOPICS
This unit starts with a detailed investigation of the basic electrical and physical properties of Metal OxideSemiconductor (MOS) systems, upon which the MOSFET structure is based. We will consider the effects ofexternal bias conditions on charge distribution in the MOS system and on the conductance of free carriers. Itwill be shown that, in field effect devices, the current flow is controlled by externally applied electric fields,

and that the operation depends only on the majority carrier flow between two device terminals. Next, thecurrent-voltage characteristics of MOS transistors will be examined in detail, including physical limitationsimposed by small device geometries and various second-order effects observed in MOSFETs. Note thatthese considerations will be particularly important for the overall performance of large-scale digital circuitsbuilt by using small-geometry MOSFET devices.

TOPIC (UNIT) TITLE Unit 2: SCALING IN MOSFETS
DESCRIPTION
The design of high-density chips in MOS VLSI (Very Large Scale Integration) technology requires that thepacking density of MOSFETs used in the circuits is as high as possible and, consequently, that the sizes ofthe transistors are as small as possible. The reduction of the size, i.e., the dimensions of MOSFETs, iscommonly referred to as scaling. It is expected that the operational characteristics of the MOS transistor willchange with the reduction of its dimensions. Also, some physical limitations eventually restrict the extent ofscaling that is practically achievable. In this unit, we will examine the constant voltage and constant fieldscaling and scaling issues in interconnects, Latch up in CMOS and methods for preventing latchup. Later wewill discuss about digital MOSFET model, series connection of MOSFETs and body effect.

TOPIC (UNIT) TITLE Unit 3: MOS INVERTERS
DESCRIPTION
In this unit, we focus on one single incarnation of the inverter gate, being the static CMOS inverter or theCMOS inverter, in short. This is certainly the most popular at present, and therefore deserves our specialattention. We analyse the gate with respect to the different design metrics:
cost, expressed by the complexity and area integrity and robustness, expressed by the static (or steady-state) behaviour performance, determined by the dynamic (or transient) response energy efficiency, set by the energy and power consumption.

Pseudo NMOS and CMOS inverters Calculation of delay times, Power dissipation for CMOS inverter Design of super buffer Pass transistors and Transmission gates

DESCRIPTION
In high-density, high-performance digital implementations where reduction of circuit delay and silicon areais a major objective, dynamic logic circuits offer several significant advantages over static logic circuits.The operation of all dynamic logic gates depends on temporary (transient) storage of charge in parasiticnode capacitances, instead of relying on steady-state circuit behavior. In this unit, we will examine theDynamic CMOS circuits, Solutions for charge sharing, Method of Logical Effort for high speed CMOSdesign. Later we will discuss about BiCMOS logic circuits, Simple gates using BiCMOS.

TOPIC (UNIT) TITLE Unit 5: CMOS CLOCKING STYLES
DESCRIPTION
The need for low-power design is also becoming a major issue in high-performance digital systems, such asmicroprocessors, digital signal processors (DSPs) and other applications. The common traits of high-performance chips are the high integration density and the high clock frequency. The power dissipation ofthe chip, and thus, the temperature, increases with the increasing clock frequency. In this unit, we willprimarily concentrate on the circuit- or transistor-level design measures which can be applied to reduce thepower dissipation of digital integrated circuits.The input/output (VO) circuits, clock generation, and distribution circuits are essential to VLSI chip design.The design quality of these circuits is a critical factor that determines the reliability, signal integrity, andinter chip communication speed of the chip in a systems environment.
