Abstract:
1. A transmission circuit transmitting deferential signals via first and second signal lines constituting a differential pair, comprising: a current source coupled between a first power source and a given node; a first transistor formed between the first signal line and the node; a second transistor formed between the second signal line and the node; a first buffer outputting a first control signal to the gate of the first transistor; and a second buffer outputting a second control signal to the gate of the second transistor, wherein when any of the first control signal and the second control signal is set active, other of these control signals is set non-active; each of the first and second buffers includes a first inverter and a second inverter receiving an output from the first inverter; and a capacitance-arrangement circuit is installed between the first inverter and the second inverter.
