Design analog blocks, systems or sub-systems using a combination of behavioral modeling tools and transistor level circuit design tools. Must be capable of implementing and optimizing circuit architectures and transistor-level circuit solutions to achieve a variety of challenging noise, distortion, power consumption and cost requirements. Help take responsibility for projects with teams of analog engineers. Draw or oversee the drawing of the custom physical layout of these circuits. Work with others to define circuit board components to be used with these circuits. Define requirements for internal chip interfaces between the analog and digital circuits. Review the chip package pinout / ballout and review and revise the chip package route with package layout engineers. Design and/or review the PC test board schematics used for testing the IC performance. Characterize the performance of these ICs using lab equipment. Debug performance problems found during characterization of these analog circuits. Work with automatic test engineers (ATE) to develop production tests for these circuits. Document the operation and performance of these analog circuits.
