Driven by advanced CMOS technology, power management units, RF transceivers, and sensors, analog and mixed-signal circuits can now be fully integrated with VLSI digital systems for applications ranging from mobile, internet-of-things (IoT), wearable, and implantable medical devices. Evidently, the circuit- and system-level innovations have pushed the device performance boundaries to become orders of magnitude higher, whilst keeping the same or even lower power consumption. Selected Topic in Power, RF, and Mixed-Signal ICs provides a practical overview and state-of-the-art advancements on several selected topics in the areas of power, RF, and mixed-signal integrated circuits and systems. Topics covered in the book include: Very-High-Frequency DC-DC Switching Converters Analog and Digital Low-Dropout Regulators Analog and Digital Sub-Sampling Frequency Synthesizers Hybrid ADC Architecture with Digital Assisted Techniques CMOS Image Sensors and Their Biomedical Applications CMOS Temperature Sensors CMOS Millimeter-Wave Power Amplifiers Zigbee/BLE Transmitter for IoT Applications
