Abstract
The main topic of the previous chapters was variations on the circuit level and the available adaptive techniques to combat those variations. As discussed in chapter 1, circuit level variations are variations encountered during the design of each individual circuit block in a system. Those variations are essentially the variations in the absolute values of the basic parameters of devices (resistors, capacitors, and transistors) due to process, supply voltage, and temperature variations. This chapter focuses on variations on the network level, i.e. variations in the transmission media. As mentioned in chapter 1, one of the major problems with any transmission media used for digital communications is Intersymbol Interference, ISI for short. This chapter will give an overview of the causes of ISI and its effect on the reception quality of digital data. The available techniques for combating ISI, particularly equalization, including fixed and adaptive equalization will be discussed. A comparison between analog and digital implementations of equalization techniques will be presented along with the advantages and disadvantages of both methodologies. Chapter 7 will present the implementation of an analog adaptive equalizer for wire line transceivers.
