CMOS Optical Preamplifier Design Using Graphical Circuit Analysis

1.2 Thesis Outline 7
technique called dynamic gate biasing (DGB) that uses charge pumps for the stable
biasing of transistors. The challenge of analyzing the low-voltage transimpedance
amplifier is highlighted to motivate the discussion of graphical circuit analysis in
Chapter 4.

Chapter 4 presents the DPI/SFG analysis method. The chapter begins with a his-
tory of the technique and discusses its current limitations. It then presents a general
formulation of the method based on Kirchhoff’s Current Law. Numerous examples
are presented to aid the reader with the details of the technique and to highlight its
ability to provide insight into a circuit’s operation.
Chapter 5 applies the DPI/SFG analysis method to the design and optimization
of the low-voltage transimpedance amplifier introduced in Chapter 3. The design
process and the ability of DPI/SFG analysis to provide insight into the operation of
circuits is emphasized.
Chapter 6 presents the implementation details and experimental results of two
fabricated integrated circuits that were used to verify the proposed preamplifier
designs. Finally, in Chapter 7, the thesis is summarized and directions for future
work are discussed.
