    摘要: A semiconductor device including a tristate buffer circuit, which includes, on an output stage, at least a first transistor (P1) for pull-up driving and a second transistor (N1) for pull-down driving, in which, when a control signal (EN) is of a value indicating an enable state, an output is set to a high level or to a low level, depending on a data signal, and in which, when the control signal is of a value indicating a disable state, the first and second transistors are turned off to set a high impedance state of the output. The semiconductor device further includes a control unit (120, P6, P7) for performing control for speeding up the transition from the on-state to the off-state of the first transistor (P1) at the time of switching the control signal (EN) from the enable state to the disable state.

    摘要: Method and circuitry for converting a differential logic signal to a single-ended logic signal eliminate slower PMOS transistors and speed up the conversion process. In specific embodiments differential logic signals of the type employed in, for example, current-controlled complementary metal-oxide-semiconductor (C3MOS) logic are converted to single-ended rail-to-rail CMOS logic levels using a differential pair of NMOS transistors (M1,M2) with resistors (R1,R2) as load devices and an NMOS current source transistor (M3) that provides dynamically adjusted tail current.

    摘要: Une Interface de bus comportant un premier circuit basée sur une première paire de transistors (10, 20) de type opposés présentant une électrode de commande et une électrode commune destinée à fournir à premier potentiel de sortie (D+). Un second circuit comporte une seconde paire de transistors (30, 40) de type opposés au présent et qui présentant une électrode commune destinée à fournir un second potentiel (D-) commutant dans un sens inverse au précédent. Le dispositif comporte des premiers moyens de couplage capacitifs destinés à réinjecter une fraction du signal existant audit premier potentiel (D+) dans lesdites électrode de commandes de ladite seconde paire de transistors et des seconds moyens de couplage capacitifs destinés à réinjecter une fraction du signal existant audit second potentiel (D-) dans lesdites électrodes de commande de ladite première paire de transistor. On arrive ainsi à compenser les décalage de temps de montée et de descente des transistors de chaque paire.

    摘要: A buffer, driver, or level-shifting circuit having an input (IN) connected to signal inputs (51, 53) of a pair of comparators (41, 43) and an output (OUT) connected between a pair of pull-up and pull-down transistors (45, 47) controlled by the comparators. A first reference voltage applied to the reference input (55) of the comparator (41) controlling the pull-up transistor (45) is selected to be less than the nominal transition point of the circuit, while a second reference voltage applied to the reference input (53) of the comparator (43) controlling the pull-down transistor (47) is selected to be greater than the nominal transition point of the circuit, thereby allowing the circuit to recognize the beginning of the signal transitions on its input sooner.
