    摘要: The invention relates to an electronic circuit comprising differential signal input means, a combining stage, a discriminating stage and differential signal output means. The discriminating stage comprises four transistors (Q8, Q9, Q10, Q11) each having first electrodes (83, 93, 103, 113) and second electrodes (81, 91, 101, 111) and a respective gate electrode (82, 92, 102, 112). The first electrodes of said four transistors are connected to a common node. The combining stage is arranged to convert differential input signals into gate signals applied to the gate electrodes of some of said four transistors respectively.

    摘要: The invention relates to a flip-flop circuit assembly comprising at least four differential amplifiers (1, 2, 3, 4) which are interconnected in such a way that a flip-flop D is formed. According to said invention principle, the emitter nodes (E1, E2) of the differential amplifiers (1, 2, 3, 4) are switched by means of the pair of switches (S1, S2) with respect to a power potential and are controlled by a differential input clock signal applied to a control input (CN, CP). The inventive flip-flop operates at a particularly low power voltage (VCC) and is particularly suitable for designing frequency dividers and shift registers.

    摘要: A DC-coupled active pull-down ECL circuit ("LS-APD") has a pull-down drive that self adjusts to lead conditions. A current source (Q3) sinks emitter current from first (Q1) and second (Q2) bipolar transistors. The input signal (IN) is coupled to the base of the first transistor, whose collector signal is coupled to the base of a pull-up transistor (Qpu) whose emitter is the LS-APD output voltage node (OUT). The pull-up transistor is coupled between the upper rail (Vcc) and the second transistor's collector load resistor (R2). A pull-down transistor (Qpd) has its base coupled to the second transistor's collector, its collector coupled to the LS-APD output node, and its emitter coupled to a node receiving a regulated (Vreg) voltage. As load capacitance increases, the output voltage takes longer to drop sufficiently to turn off the pull-down transistor.

    摘要: A new family of current mode logic (CML) gates (14) which, in one embodiment includes OR/NOR and AND/NAND gates, as well as more complex logic functions. The circuit uses a complementary signal to drive the gate of a feedback transistor (19) which has the effect of pseudo differential operation. Although it uses only single-ended inputs (A, B), because of this feedback aspect, the circuit has many of the advantages of a differential circuit such as low-voltage operation, higher immunity to noise, and less sensitivity to parasitic elements.
