Abstract:
A circuit for shifting at least one input switching signal includes a CMOS bistable circuit having two branches, and a circuit for accelerating the switching of the bistable circuit. The circuit for accelerating the switching allows an output transistor of each branch to be switched to the off state when an input transistor of the branch switches to the on state. The circuit for accelerating switching includes, for at least one given branch, an associated current mirror generating a turn-off current for the output transistor of the branch on the basis of a turn-on current for the input transistor of the branch.
Abstract:
An FAMOS memory includes memory cells, with each memory cell including an insulated gate transistor, and a first access transistor having a drain connected to a source of the insulated gate transistor. The FAMOS memory also includes an insulation transistor having a drain and a source respectively connected to the source of the insulated gate transistors of two adjacent cells of a same row. Each insulated gate transistor has a ring structure, and a ladder-shaped separation region insulates the cells of the same row.
Abstract:
A computer system for executing instructions having assigned guard indicators, comprises instruction supply circuitry, pipelined execution units for receiving instructions from the supply circuitry together with at least one guard indicator selected from a set of guard indicators, the execution unit including a master guard value store containing master values for the guard indicators, and circuitry for resolving the guard values in the execution pipeline and providing a signal to indicate whether the pipeline is committed to the execution of the instruction, and an emulator having watch circuitry for effecting a watch on selected instructions supplied to the execution pipeline and synchronising circuitry for correlating resolution of the guard indicator of each selected instruction with a program count for that instruction.
Abstract:
A wideband differential amplifier includes a first differential stage connected to a Miller stage allowing an open-loop gain increase. The Miller stage includes a current source and a resistive-capacitive network causing a feedback into the current source. The feedback includes a portion of a Miller stage output signal having a high frequency range to move a bias point of the current source within the high frequency range. Thus, a gain of the Miller stage significantly increases towards the bias point.
Abstract:
Process for fabricating a component, such as a capacitor in an integrated circuit, and integrated component, in which process and component a first electrode is in the form of a cup; a layer made of a dielectric covers at least the wall of the first electrode; a second electrode fills the cup; a first electrical connection via lies above the second electrode; and a second electrical connection via lies laterally with respect to and at a predetermined distance from the first electrode and is connected to the first electrode.
Abstract:
A processing unit is associated with a first FIFO-type memory and with a second FIFO-type memory. Each instruction for loading memory stored data into a register within the processing unit is stored in the first FIFO-type memory, and other operative instructions are stored in the second FIFO-type memory. An operative instruction involving the register is removed from the second FIFO-type memory if no loading instruction which is earlier in time, and intended to modify a value of the register associated with this operative instruction is present in the first FIFO-type memory. In the presence of such an earlier loading instruction, the operative instruction is removed from the second FIFO-type memory only after the loading instruction has been removed from the first FIFO-type memory.
Abstract:
A voltage-switching device includes a high-voltage translator connected to a high-voltage node receiving either a low-voltage logic level or a high-voltage level as a function of a low-voltage/high-voltage mode control signal to provide at least one output signal as a function of this mode control signal and of a switching control signal. A voltage-level switching circuit is controlled by output signals from the high-voltage translator and by the mode control signal and the switching control signal for application, as output voltage levels, of either ground or the low-voltage logic level in low-voltage mode or the high-voltage level in high-voltage mode.
Abstract:
A device for detecting a defective power supply connection in an integrated circuit includes a comparison circuit for comparing voltage levels of an input/output pad of the integrated circuit and an internal power supply line connected to a power supply pad of the integrated circuit. A pull-down or pull-up device is connected between the input/output pad and the internal power supply line.
Abstract:
The source, drain and channel regions are produced in a silicon layer completely isolated vertically from a carrier substrate by an insulating layer, and are bounded laterally by a lateral isolation region of the shallow trench type.
Abstract:
A memory implementing an incremental address counter is sequentially read. An address jump includes detecting an address jump signal, incrementing the incremental address counter, and reading the content of the memory at the incremented address. The content read at the incremented address is transferred into the incremental address counter, and the content of the memory is read at the address contained in the incremental address counter.
