Synthesis Procedure of Configurable Building Block-Based Linear and Nonlinear Analog Circuits

Synthesis and design methodology suitable for computer-aided design tools are now emerging as major challenge for analog system designers. This paper proposes a systematic synthesis procedure which provides reusability and programmability, for linear and nonlinear analog circuits using configurable building block (CBB) and analog cell (AC). Operational transconductance amplifier-based ACs are synthesized in terms of CBBs. Reusability and programmability of the synthesis methodology have been demonstrated by realizing different types of linear and nonlinear circuits and mapping those circuits in field programmable analog array. Finally, the proposed methodology has been integrated as an electronic design automation tool AnaSyn1.0. Performance of all the proposed circuits has been verified by SPICE simulation.
