Abstract
A variable delay element includes first and second input stages, each input stage comprising a charge pumping circuit and a discharging circuit, each charge pumping circuit and each discharging circuit associated with the first and second input stages configured to operate on opposite phases of an input signal, and an output stage comprising at least two transistors. The transistors are independently controlled by the first and second input stages and produce an output signal which is a delayed version of the input signal.
