  • Switching circuit
    Patent number: 4614897
    Abstract: An electronic switch is disclosed that uses two complementary regenerative latches connected in a push-pull arrangement. The latches are interconnected so that when either latch turns on, the other latch is forced to turn off. In this arrangement, the inherently short turn-on time of each regenerative latch translates to a shortened turn-off time of the other latch. The switch is disclosed in the context of a fluorescent lamp ballast and dimmer circuit.
