Abstract
A transmission circuit, which transmits a differential signal having pulse time larger than a predetermined minimum pulse time, includes: a driving unit for feeding the differential signal as a potential difference between two transmission lines; a driven unit for operating on the basis of the differential signal by receiving the differential signal by the potential difference between the two transmission lines; and a connecting resistor for electrically connecting the two transmission lines. Further, a connecting MOS transistor may be provided near a receiving end of the driven unit.
Claims3
A transmission circuit, which transmits a differential signal having pulse time larger than a predetermined minimum pulse time, comprising:
- a plurality of driving units, each of which feeding the differential signal as a potential difference between two transmission lines;
- a plurality of driven units, each of which operating on the basis of the differential signal by receiving the differential signal by the potential difference between the two transmission lines;
- and
- a plurality of connecting MOS transistors, each of which electrically connecting the two transmission lines by receiving a predetermined voltage through its gate terminal, each of its source terminal and drain terminal being electrically connected with one of the two transmission lines,
- wherein the plurality of driving units, the plurality of driven units, and the plurality of connecting MOS transistors are connected with each other in series via the two transmission lines.
