Abstract
Due to the lack of proper design automation tools, designers are often forced to use full-custom design methodologies when designing analog and mixed-signal circuits. In this work, we discuss a design methodology based on parameterized cells intended for efficient design. The methodology is illustrated with the design of a 12-bit configurable current-steering DAC. Because the cells are parameterized, their layout must be described in a generalized way, resulting in a longer design time compared with a manual layout of a fixed circuit. However, the parameterized approach simplifies iteration of the layout process and block reuse.
