Abstract

A system including first voltage supply circuitry configured to provide a first voltage supply with spurious frequency content and second voltage supply circuitry configured to provide a second voltage supply without the spurious frequency content is provided. The system includes signal generation circuitry configured to generate a first digital signal using a clock signal and the first voltage supply and configured to cause the spurious frequency content on the first voltage supply and output circuitry configured to generate a second digital signal from the first digital signal synchronous with the clock signal using the second voltage supply.
