Abstract
An adaptive clock generation circuit for synthesizing Time-Average-Frequency in dynamic fashion includes (a) a timing circuit for generating a base unit of fixed time span, (b) a control circuit that takes inputs from a microelectronic system wherein the control circuit and the clock generation circuit reside, for generating a update signal and a frequency control word, (c) a direct period synthesizer for generating a plurality of types of pulses by utilizing said base unit and the frequency control word, for creating a segment of a clock pulse train by connecting electrical pulses in series that are selected from said plurality of types according to the update signal, for creating the entire clock pulse train by connecting said segment in series. The resulting Time-Average-Frequency of the clock pulse train matches a selected frequency that is required by the operation of the microelectronic system wherein the clock generation circuit resides. A method of creating such adaptive clock generation circuit is also presented.
