Analog Circuits for Biochip: Wireless Power and Data Transmission

This lecture covers the wireless power and data transmission to implanted systems, including topics such as impedance matching, inductive coupling, analog and digital modulations, active circuits, and various modulation techniques like amplitude modulation (AM) and frequency modulation (FM). The instructor discusses the advantages and disadvantages of different modulation techniques, such as noise immunity, bandwidth occupation, and complexity of implementation. Additionally, the lecture explores pulse modulation techniques, analog multiple channel modulation methods, pulse code modulation (PCM), and line encoding methods for serial data transmissions. The importance of digital modulation for noise immunity and various digital modulation types like amplitude shift keying (ASK), frequency shift keying (FSK), and phase shift keying (PSK) are also discussed.
