ABSTRACT
Nonlinear analog components in metal oxide semiconductor technology essentially include comparators and multipliers. They can find applications in communication and instrumentation systems. The basic idea of the multiplier implementation relies on applying the input signals to a nonlinear device and canceling the undesired output components. The chapter deals with the analysis and design of nonlinear active components. Generally, the objective is to achieve a sufficient dynamic range and bandwidth using sub micro meter integrated circuit process with a low supply voltage. Several circuit structures are available for the implementation of nonlinear functions, such as the comparison and multiplication. The overall power consumption of a comparator can be divided into static, dynamic, and short-circuit components. In a static comparator, there is always a low-impedance path between the output and both the supply voltage and ground, yielding an uninterrupted power consumption during the whole time that the circuit is powered up.
