ABSTRACT:
A method and device for managing metastable signals. The device includes: a first latch and a second latch, a multiple switching point circuit, connected between an output node of the first latch and an input node of the second latch, wherein the multiple switching point circuit includes at least one pull up transistor and at least one pull down transistor that are selectively activated in response to a feedback signal provided from the second latch and in response to a an output signal of the first latch such as to define at least a low switching point that is lower than a high switching point of the multiple-switching point circuit; wherein a switching point of an inverter within the first latch is between the high and low switching points.
