  • Master-slave D-type flip-flops with improved voltage offset means
    Patent number: 4825097
    Abstract: A master-slave D-type flip-flop includes a master section (14) and a slave section (16). The master section (14) has a master clock differential transistor pair formed of a first input transistor (MQ14) and a first reference transistor (MQ13) whose emitters are connected together. The slave section (16) has a slave clock differential transistor pair formed of a second input transistor (SQ9) and a second reference transistor (SQ10) whose emitters are connected together. An improved voltage offset means is provided for creating a separation of thresholds between the master section and the slave section. The offset voltage means is formed of the first input transistor (MQ14) of the master section having dual-emitters and of the second reference transistor (SQ10) of the slave section having dual-emitters.
