- Input Stages in the Frequency Domain

To complete the study of the circuits introduced in the previous chapter we need to

consider also the effect of the capacitances which are unavoidably present in such

structures. This implies addressing the frequency behavior of amplifiers, a task which

is best achieved byworking in the s-domain through the use of the Laplace transforms.

This tool should be familiar to the reader from fundamental University courses and

adequate treatments of the topic can be found in one of the many textbooks on linear

electrical network [1, 2]. The systematic analysis of MOS integrated circuits in the

frequency domain is covered in standard microelectronics textbooks [3-7].
