Mixed-Signal Verification Of A PWM Ultrasound Driver With Analog FastSPICE™ AMS At Stanford University

Designers of digitally-assisted circuits are working towards unlocking the digital signal processing capabilities of fine line CMOS technology to leverage their digital processing potential for performance recovery or enhancement in systems. This case study highlights a key challenge associated with the design of these new types of circuits.  It also describes the design and verification of a digitally-assisted ultrasound driver used for structural health monitoring as a non-destructive testing device.
