Development of analog circuit design automation tool
Vinitha Krishnamurthy, Bruce Kim · 2009
In this paper, the performance of Genetic Algorithm (GA) and the key genetic operators are evaluated to identify the most suitable combination to be adopted for automating the design of analog circuits. The GA based design approach to select component values of an analog circuit to meet the desired specifications, is discussed and successfully demonstrated using a prototypical tool. A user friendly console provides an interactive simulation environment and Berkeley SPICE is the tool used for simulating analog circuits. Design of internals of the Complementary MOSFET (CMOS) Operational Amplifier for a specified bandwidth and design of a circuit using Bipolar Junction Transistor (BJT) Operational Amplifier for a specified closed loop gain are presented as applications. The methods used are generic and can be applied to all analog circuits.
