PROBLEM TO BE SOLVED: To enhance a level difference between a high level and a low level of a conversion signal converted from an electric pulse.SOLUTION: In a transistor T1, one of the drain terminal and the source terminal is connected to a transmission line TL1, and a gate pulse is input to the gate terminal. One terminal of a capacitor C1 is connected to the other one of the drain terminal and the source terminal of the transistor T1, whereas another terminal is grounded. One terminal of a resistor R1 is connected to the other one of the drain terminal and the source terminal of the transistor T1, whereas to another terminal, a DC voltage Vchrg is supplied. In synchronization with an electric pulse propagating through a transmission line TL1, the gate pulse is input, so that a voltage according to a high/low electric pulse is retained at the capacitor C1.SELECTED DRAWING: Figure 1 |
