    摘要: Duplicated circuit arrangement comprising a main processor (30) and its P bit data bus (44), and two identical redundant devices (21 ; 22), each device is comprised of a processing element (23 ; 35) performing the same task in parallel on a P bits word, and send/receive circuits (24,25;36,37) controlled by the main processor through lines (SR11 to SR22) to transmit said word to and from said main processor. For each device, the send/receive circuits are split into two parts. Send/receive circuit of the first device (21) is split in two parts (24, 25); the first part (24) handles the P/2 Most Significant Bits (MSB's) and the second part (25) handles the P/2 Less Significant Bits (LSB's). In normal operation, during the transmission step, only the first part (24) is allowed to send bits on one half (33) of the data bus (44). Symmetrically send/receive circuit of the second device (22), is also split in two parts (36, 37); the first section (36) handles the P/2 Most Significant bits (MSB's) and the second part (37) handles the P/2 Less Significant Bits (LSB's); only the second part (37) is allowed to send bits on the other half (34) of the data bus (44). Therefore, the data bus driving effort is equally shared between the two devices, the maximum number of simultaneous switching is P/2 for each device. This reduction allows greater transmission speed on large busses.

    摘要: According to the present invention, a CMOS interface circuit (C2) similar to a latch made by two CMOS cross coupled inverters (INV1, INV2) is placed directly on the output node (14) of conventional BICMOS logic circuit (11) operating alone in a partial swing mode. This latch is made of four FETs P5, P6, N8, N9 cross-coupled in a con­ventional way with the feedback loop connected to said output node (14) The partial voltage swing (VBE to VH-VBE) naturally given by the output bipolar transistors (T1, T2) mounted in an push pull configuration is rein­forced to full swing (GND to VH) by the latch at the end of each transition The state of the output node is forced by the latch because of the high driving capability due to the presence of said output bipolar transistors (T1, T2). As a result, the improved BICMOS logic circuit (D2) has an output signal (S) that ranges within the desired full swing voltage at the output terminal (15). It is a charac­teristic of this embodiment that the structure of CMOS interface circuit (C2) is always independent of the logic function implemented in the conventional BICMOS logic circuit (11). More generally, the CMOS interface circuit may have various physical implementations, however, it is always comprised of CMOS FETs and it becomes active at least in one of the GND to VBE or (VH - BE) to VH range.

    摘要: A high speed high sensitivity receiver comprising a latch (11) between ground and a strobe signal which provides its power supply and a controlled gating circuit (12) comprised of two transmission gates (TG1, TG2). One (TG1) is connected to the line input signal IN the other (TG2) is connected to a reference voltage REF.
    Supply of the latch and turning on/of of the gating device are activated by STOBE and signals.
    Assuming the strobe is at a low level, e.g. at the ground potential, no current is supplied to the latch composed of four transistors (T1,T2,T3,T4), but the transmission gates (TG1 and TG2) are on, connecting OUTC to REF and OUT to IN.
    A latching operation between the cross coupled transistors (T1,T2,T3,T4) is started as soon as the strobe is pulled up. The latching operation is then completed when transmission gates (TG1 and TG2) are turned off (after a transit time of the strobe through the inverter T5/T6). The final state depends on the initial condition found on OUT (node A) and OUTC (node B). T1 turns on first, if IN and OUT are lower than REF and OUTC, and vice-versa.
    The nodes A and B are pulled quickly to the levels defined by REF and IN when the strobe is switched down, since the latch supply voltage is suppressed and transmission gates (TG1 and TG2) being turned on.
