Abstract
A technique for reducing the likelihood that a frequency detector will incorrectly assert control over a VCO because of metastable-induced errors involves qualifying frequency detector control signals by requiring multiple consecutive control signals that indicate the frequency detector should assert control over the VCO before the frequency detector is allowed to assert control over the VCO. In an embodiment, the frequency detector control signals are qualified by a series of full-swing library cell flip-flops.
