Title: Input buffer circuit
Inventor: IWASHITA SHINICHI
IPC: H01L21/8238
Filed: 1990-08-20
Abstract: PURPOSE:To prevent the malfunction of the circuit by feeding back the output of a semiconductor integrated circuit to an input level compensation circuit section through a delay circuit and providing a signal transition detection circuit between the delay circuit and input level compensation circuit section. CONSTITUTION:The output of an inverter 3 is inputted to the gates of MOS transistors through a positive-phase delay circuit 6. Since noise is inputted during the period from time T0 to time T1 while the input Ai to this input buffer circuit is high in level, namely, while the output A0 of the inverter 3 is high in level, the internal logic of the input buffer circuit is inverted. Since the gate potential of a PMOS and NMOS transistors P3 and N3 does not change or makes a very small change during the period from T0 to T1 during which the internal logic is inverted due to the noise, the logical threshold of the input buffer circuit does not shift while the noise is generated.

Title: Reference voltage circuit
Inventor: MORITA YASUSHIGE
IPC: G05F3/24
Filed: 1987-09-01
Abstract: PURPOSE:To obtain a highly accurate reference potential by setting a circuit between a reference potential generating means and an output transistor TR to compensate the threshold value of this TR so that the error caused by the fluctuation of the power supply voltage between the output potential and the reference potential is eliminated. CONSTITUTION:The resistance R1 and R2 are connected in parallel between a power supply terminal 1 and the ground so that an accurate reference potential is produced at a node point N1. A TR Q1 connected to the point N1 produces a potential at a node point N2 which is higher than the potential of the point N1 by a degree equal to the threshold voltage VTH of the TR Q1. In the same way, a TR Q2 connected to the point N1 produces the voltage at a node point N3 which is lower than the potential of the point N1 by a degree equal to the threshold voltage VTP of the TR Q2. Then a potential lower than that of the potential of the point N2 by a degree equal to the threshold voltage VTN a TR Q3 is outputted to an output terminal 2 by the TR Q3 connected to the point N2. Therefore an accurate reference potential RV1 which is free from dependence on the threshold voltages of the TR Q1-Q4 is obtained at the terminal 2 as long as both voltages VTN and VTP have no fluctuation.

Title: Repeater
Inventor: NAKAJIMA MASAHIRO
IPC: H04J3/08
Filed: 1987-09-02
Abstract: PURPOSE:To attain normal restoration after fault recovery in a short time, by selecting a synchronizing signal from a pre-stage as it is as an output in response to the detection output of a fault when a multi-stage repeater detects the fault of a means synchronizing with an input signal from the pre-stage. CONSTITUTION:An input signal 1 from the pre-stage is given to a frame synchronizing circuit 100 and a switching circuit 102 of a repeater 7. The frame synchronizing circuit 100 takes frame synchronization with the input signal 1 to extract a redundancy signal or an auxiliary signal and inserts an auxiliary signal 2. When no error exists in the circuit 100, the output 6 of the synchronizing circuit 100 is sent to the post-stage via a switching circuit 102. When a fault detection circuit 101 uses a monitoring signal 3 to detect the fault of the circuit 100, the switching signal 5 is sent to the switching circuit 102 to output the input signal 1 from the prestage to the post-stage as it is. When the fault is recovered, the state is restored into the initial state and the signal 6 is outputted (4) to the post-stage. Thus, the time of the frame synchronization in all repeaters at the restoration of fault is shortened.
