<p>PURPOSE: To reduce the power consumption and the occupied area of an integrated circuit device by suppressing the reflection caused by load of the signal that is transmitted through a transmission line by means of the signal that is inputted to the load at an output end part of the transmission line. CONSTITUTION: An integrated circuit device consists of a transmission line 2, a reflection suppression circuit 3, a voltage variation suppression circuit 5, a detection part 6, a delay circuit 7, a control part 8, etc. In such a constitution, the signals generated by a signal source 1 are inputted to the line 2 and transmitted through this line. The signals transmitted through the line 2 are inputted to the load 4 via the circuit 3. At the same time, the part 6 detects that the voltage has sharp variation at a level higher or lower than the power voltage at an output end part of the line 2. The circuit 7 delays the signal that is inputted at the termination of the line 2 and inputs this signal to the part 8. The part 8 controls the circuit 5 based on the delayed signal and then suppresses the voltage variation at the timing when the signals have sharp vibrations at the termination of the line 2. Therefore, the circuit 3 consists of an active circuit, so that the power is saved and the scale is reduced for the integrated circuit device.</p> |
