Abstract

Conventional methods of generating accurate on-chip frequencies are based on electrical components such as resistors, capacitors, and inductors. Recently, a new type of frequency reference based on the thermal diffusivity (TD) of silicon has been introduced. Such TD frequency references rely on the well defined thermal-domain properties of silicon, rather than on the stability of electrical components. This thesis explores various ways of improving the performance of TD frequency references.
