ABSTRACT:
An apparatus and method for instantaneously stretching multi-phase clock signals includes a delay line to generate a plurality of multi-phase clock signals. An instantaneous signal stretch logic circuit is connected to the delay line. The instantaneous signal stretch logic circuit transforms the plurality of multi-phase clock signals into stretched multi-phase clock signals in response to a filter capacitor analog signal and a digital stretch signal. Multiple embodiments of the instantaneous signal stretch logic circuit are disclosed. However, each embodiment includes dual current control paths with a single current control path responsive to the digital stretch signal, which is preferably a single bit value.
