CHAPTER 3 – MODELS FOR CMOS COMPONENTS
INTRODUCTION
Chapter Outline
3.1 – Large Signal Transistor Models
3.2 – Process, Voltage, and Temperature Variations
3.3 – Small Signal Transistor Model
3.4 – Passive Component Models
3.5 – Matching of Components
3.6 – SPICE Models
3.7 – Model Extraction
3.8 – Summary


SECTION 3.8 - SUMMARY
• Model philosophy for analog IC design
Use simple models for design and sophisticated models for verification
• Models have several parts
Large signal static (dc variables)
Small signal static (midband gains, resistances)
Small signal dynamic (frequency response, noise)
Large signal dynamic (slew rate)
• In addition models may include:
Temperature
Noise
Process variations (Monte Carlo methods)
• Computer models
Must be numerically efficient
Quickly derived from new technology
• Analog Design “Tricks”
Stay away from minimum channel length if possible
- Larger rds 􀀁 larger gains
- Better agreement
Don’t use the computer models for design, rather verification of design

CHAPTER 4 – CMOS SUBCIRCUITS
INTRODUCTION
Chapter Outline
4.1 MOS Switch
4.2 MOS Diode/Resistor
4.3 Current Sinks and Sources
4.4 Current Mirrors
4.5 Current and Voltage References
4.6 Bandgap Reference
Goal
To develop an understanding of the subcircuits used in CMOS analog circuit design.
What is a subcircuit?
A subcircuit is a circuit primitive used in building other circuits. A subcircuit cannot
typically stand by itself but needs to be connected to other subcircuits to implement a
circuit function.


SUMMARY OF VOLTAGE AND CURRENT REFERENCES
• Reasonably good, simple references are possible
• Best power supply sensitivity is approximately 0.01
(10% change in power supply causes a 0.1% change in reference)
• Typical simple reference temperature dependence is 􀀁 1000 ppm/°C
• Can obtain zero temperature coefficient over a limited range of operation
• Bandgap voltage references can achieve temperature dependence less than 50 ppm/°C
• Correction of second-order effects in the bandgap voltage reference can achieve very
stable (1 ppm/°C) voltage references.
• Watch out for second-order effects such as noise when using the bandgap voltage
reference in sensitive applications.

CHAPTER 6 – CMOS OPERATIONAL AMPLIFIERS

INTRODUCTION
Chapter Outline
6.1 CMOS Op Amps
6.2 Compensation of Op Amps
6.3 Two-Stage Operational Amplifier Design
6.4 Cascode Op Amps
6.5 Simulation and Measurement of Op Amps
6.6 Macromodels for Op Amps
6.7 Summary
Hierarchical Perspective:
The op amps in this chapter represent an
example of a reasonable complex circuit.
The blocks and sub-blocks of the last two
chapters will be used to implement the op
amp in this chapter.


Topics
• Design of CMOS op amps
• Compensation of op amps
- Miller
- Self-compensating
- Feedforward
• Two-stage op amp design
• Cascode op amps
• Simulation and measurement of op amps
• Macromodels of op amps
Chapter Objective
Purpose of this chapter is to introduce the simple two-stage op amp and the cascode op
amp to illustrate the concepts of op amp design and to form the starting point for the
improvement of performance of the next chapter.
Design Procedures
The design procedures given in this chapter are for the purposes of understanding and
applying the design relationships and should not be followed rigorously as the designer
gains experience.

CHAPTER 7 – HIGH PERFORMANCE CMOS OP AMPS
INTRODUCTION
Chapter Outline
7.1 Buffered Op Amps
7.2 High-Speed/Frequency Op Amps
7.3 Differential Output Op Amps
7.4 Micropower Op Amp
7.5 Low-Noise Op Amps
7.6 Low Voltage Op Amps


SUMMARY
• Integrated circuit power supplies are rapidly decreasing (today 2-3Volts)
• Classical analog circuit design techniques begin to deteriorate at 1.5-2 Volts
• Approaches for lower voltage circuits:
- Use natural NMOS transistors (VT 􀀁 0.1V)
- Drive the bulk terminal
- Forward bias the bulk
- Use depeletion devices
• The dynamic range will be compressed if the noise is not also reduced
• Fortunately, the threshold reduction continues to allow the techniques of this section to
be used in today’s technology

CHAPTER 8 – COMPARATORS
INTRODUCTION
Chapter Outline
8.1 Characterization of Comparators
8.2 Two-Stage, Open-Loop Comparators
8.3 Other Open-Loop Comparators
8.4 Improving the Performance of Open-Loop Comparators
8.5 Discrete-Time Comparators
8.6 High-Speed Comparators
8.7 Summary

CHAPTER 8 - SUMMARY
Types of Comparators Presented
• High-gain, open-loop
• Improved high-gain, open-loop, comparators
Hysteresis
Autozeroing
• Regenerative comparators
• High-speed comparators
Performance Characterization
• Propagation delay time
• Binary output swing
• Input resolution and/or gain
• Input offset voltage
• Power dissipation
Important Principles
• The speed of the comparator depends on the linear and slewing responses
• The dc input offset voltage depends on the matching and is reduced by autozeroing.
Charge injection is the limit of autozeroing
• The comparator gain should be large enough for a binary output when vin = Vin(min)
• High speed comparator use preamplifiers cascaded with a latch
