Abstract
A frequency doubler circuit includes first and second arrangements of switches connected to the positive and negative inputs of a comparator, respectively, and arranged in such a way that first and third voltages during the first phase of a reference clock signal and second and fourth voltages during a second phase opposite to the first phase are applied to the positive and negative inputs, where the first and second voltages and the third and fourth voltages are shifted with respect to each other at a half-period of the reference clock signal and the ratio between slopes of the voltages is fixed with respect to a selected current.
