Abstract
Frequency modulated radios are widely used in ultralow power wireless designs due to their flexibility in power/performance trade-off. Their superior performance in multiple access and interference resilience makes them adaptable in both proprietary and standard compliant designs. This chapter explores the theoretical limits and constraints of frequency-modulated radios from the system level architecture to key subsystem blocks: the local oscillator and the power amplifier. The local oscillator, usually implemented with frequency synthesizer subsystem, is one of the most power hungry and complicated blocks that not only constraints RF performance but also offers subtle scalability with power. The power amplifier, on the other hand, directly affects communication link budget and system efficiency. This chapter will cover basic design methodologies and tradeoffs of frequency synthesizer and power amplifier in ultralow-power-frequency-modulated transmitters. A ring oscillator-based Bluetooth low-energy transmitter will be shown as a design example.
