Abstract

Synchronizer circuits having controllable metastability are provided, one of which includes: a first flip-flop circuit comprising a first master latch connected in series with a first slave latch; and a second flip-flop circuit comprising a second master latch connected in series with a second slave latch, wherein an output of the first flip-flop circuit is connected to an input of the second flip-flop circuit, at least a portion of the first flip-flop circuit is implemented in a first PWell isolated by an underlying a deep isolation NWell, at least a portion of the first flip-flop circuit is implemented in a first NWell that electrically contacts the deep isolation NWell, the first NWell is connected to a first bias voltage that is less than a positive power supply voltage, and the first PWell is connected to a second bias voltage that is greater than a negative power supply voltage.
