Design and analysis of CMOS analog signal processing circuits by means of a graphical MOST model

A graphical representation of a simple MOST (metal-oxide-semiconductor transistor) model for the analysis of analog MOS circuits operating in strong inversion is given. It visualizes the principles of signal-processing techniques depending on the characteristics of an MOS transistor. Several linearization techniques as well as a multiplying principle become transparent at the hand of the graphical representation. In the examples, special attention is focused on continuous-time filter techniques. The basis of MOSFET-C continuous-time filters and CMOS square-law circuits are explained using the graphical MOST characteristics representation.<
