摘要： Device for cancelling the effects of the reflection in a signal transmission system (10) including a driver (12) and a plurality of n receivers (14, 16) wherein signals are sent according to a multipoint topology from the driver to the receivers, each receiver having an internal capacitance and sending back reflection signals to the driver each time a signal is transmitted thereto by the driver. The device comprises circuit means causing the signal resulting from the sequential reflections due to a given receiver and then due to the driver to have the same magnitude but the reverse sign as the sum of all signals received in the given receiver resulting from the reflections due to all receivers, and the net linking the driver to each receiver comprises delay means (40) enabling the propagating time of a signal sent from the driver to this receiver to be identical for each receiver, whereby the total sum of all reflection signals arriving in the given receiver at the same time is equal to zero.

摘要： A monolithic module acting as the interface between a modem and leased ("LL") or switched ("SL") telephone lines, mainly characterized in that: 1. It can be formed on a silicon chip (due to the absence of electromechanical relays or similar switching means), and 2. Its architecture is such that it makes it possible, by interconnecting or "stacking" identical modules, not only to attach additional telephone lines, but also to increase the number of allowable modem configurations. The module (10, 10') comprises two controlled-type line amplifiers (DLL, DSL) which exhibit a high output impedance regardless of whether the power supplies are "on" or "off"; two controlled-type line receivers (RSL, RLL) which provide a very high input impedance whether the power supplies are "on" or "off"; and a wrap receiver (WRP) for testing the modem (to the exclusion of the telephone lines) and interconnecting or "stacking" identical modules. The figure shows an embodiment wherein two of the modules are interconnected; various configurations can be obtained depending on the logic state of the control inputs (1 to 4 for module 10 and 1' to 4' for module 10') supplied by the modem.

摘要： A device implemented in a N-bit digital-to-analog converter (DAC) to extend its resolution to N+P bits. The N-bit DAC comprises a resistive string 2 made of 2.sup.N resistive elements R1 to R16. MSB switches in block 10 and LSB switches in block 12, when closed in response to combinations of the N-bits provide the voltage at one of taps N1 to N16 to node M1. The device comprises a string 18 made of 2.sup.P-2 elements connected between nodes M1 and M7, additional LSB switch block 14 and additional MSB switches SW4-2, SW8-2, SW12-2 and SW16-2 which are closed in response to combinations of the N-bits to connect the string 18 across the taps of a selected resistor R1 to R16. The voltage generated at one of the taps M1 to M7 of string 18 is provided to the (N+P)-bit DAC output 20 by means of one of the switches in block 16. The main advantages of this device are that the monotonicity of the conversion is not impaired by the extension to (N+P) bits, and that it is not space consuming when integrated in a chip. Furthermore, various conversion capabilities may be provided by controlling the switch SW21 and the switches in block 16.

摘要： A voltage comparator circuit with a wide common mode input voltage range which extends beyond supply voltage parameter values. The comparator circuit utilizes an input stage having two input transistors, the emitter electrodes of which are connected to receive input signals and the collector electrodes of which are connected to two current sources. A current fixing circuit is coupled to the collector electrodes of said two input transistors and acts to fix the direct current in the collector circuits at a first value IO and the currents supplied by the current sources at a second value k IO, where k is greater than 2. An output stage is provided with two input circuits respectively connected to the collector electrodes of the two input transistors and with a logic circuit arrangement set to either one of two logic levels in accordance with the sign of the difference in the voltages applied to the pair of emitter electrodes of the two input transistors.

摘要： A digital signal distribution system for distributing digital signals to remote points of a machine. It is comprised of a distribution device arranged at each of said points. In each device, a receiver receives on its true and complementary inputs, the signal to be distributed. The drivers are connected to the receivers through a crossed connection, the true output of the receiver being connected to the complementary input of the driver, and the complementary output of the receiver being connected to the true input of the driver, so as to cancel the skew of the pulse width of the signal to be distributed. The signals on outputs of the driver circuits can be utilized locally or transmitted to another remote point.
