Abstract
A flip-flop has a master section (74) comprising two transistors (40, 48). The second transistor (48) has two emitters, the second emitter conducting in response to a metastable condition wherein both transistors (40,48) are conducting concurrently, resulting in a metastable output. The second emitter (76) draws additional current through the second transistor (48) after a delay provided by a second clock (78), thus disrupting the equilibrium of the master section (74). By drawing additional current, the second transistor (48) will turn the first transistor (40) off, enabling a valid output.
