Recently, there has been an increasing push to make everything wireless. In contrast to high-performance cellular communication, where the demand for enormous quantities of data is skyrocketing, these small wireless sensor and actuator nodes require low power, low cost, and a high degree of system integration. A typical CMOS system-on-chip requires a number of off-chip components for proper operation, namely, a crystal oscillator to act as an accurate frequency reference, and an antenna. The primary goal of this thesis is to address the hurdles associated with operating without these...
