Description

This lecture covers the design and operation of analog circuits for biochip applications, focusing on wireless power and data transmission to implanted systems. Topics include system architecture, impedance matching, inductive and capacitive coupling, ultrasound and optical power coupling, and far-field telemetry. Different receiver architectures such as coherent, non-coherent, super-heterodyne, and super-regenerative are discussed, along with considerations for power receivers. The lecture also explores the use of inductors, super-regenerative oscillators, and rectifiers in wireless circuits, emphasizing the importance of impedance matching and power optimization. Practical examples and design parameters for implantable devices are presented, highlighting the challenges and opportunities in wireless data and power telemetry research.
