Summary:This paper presents compelling reasons for "digitally assisting" analog functions and important design considerations. ADCs, power amplifier, and MEMS accelerometer are used as examples. In a variety of analog circuits, "digital assistance" can be used to offload accuracy constraints to a digital processor. Key benefits are lower power and potentially higher speed and compatibility with "ultimately scaled CMOS" while key challenges are interdisciplinary nature of design problem; device modeling, circuit design, signal processing algorithms, and consideration of application layer; and design complexity and turnaround time
