The application of silicon-on-silicon MCMs to advanced analog power controllers

A mixed signal power controller is implemented in a silicon-on-silicon MCM. The application is space limited, in which a discrete component implementation is physically large and costly. A large number of passive components (resistors and capacitors) are integrated into a silicon substrate with flip-chip analog ICs. Operational characteristics of the controller are verified after integration and are compared to the discrete version. High voltage isolation requirements and interference and noise issues are studied to determine the most critical portions of the MCM layout and design.
