ABSTRACT:
A pulse generator includes a first current control circuit, and a first transistor having a source coupled to a first power supply line via the first current control circuit, a drain and a gate. A second transistor has a gate connected to the gate of the first transistor, a drain connected to the drain of the first transistor, and a source connected to a second power supply line. The second transistor has a conduction type different from that of the first transistor. An input terminal is connected to the gates of the first and second transistors. An input signal is applied to the input terminal. An output terminal is connected to the first current control circuit. An output pulse indicative of a change in the input signal is output via the output terminal.
