<p>This thesis deals with the study and comparison of on-chip LC Oscillators, used in energy recovery clocking, in terms of Power, Area of Inductor and change in load capacitance. Simulations show how the frequency of the two oscillators varies when the load capacitance is changed from 5pF to 105pF for a given network resistance. A conventional driver is used as a reference for comparisons of power consumptions of the two oscillators. It has been shown that the efficiency of the two oscillators can exceed that of a conventional driver provided the distribution network resistance is low and the on-chip inductor has a high enough Q value. Conclusions drawn from the simulations, using network resistances varying from 0Ω to 4Ω, show that the selection of the oscillator would depend on the network resistance and the amount of area available for the inductors.</p>
