Research on nanosecond pulse shaping circuits based on transmission line

A method of pulse shaping and pulse broadening is proposed.Base on the nanosecond pulse shaping circuit of ideal switch,the MOS transistor is used to replace ideal switch,in order to ensure the MOS transistor operating in the saturation region and realize the pulse shaping.When the MOS switch is in saturation region,pulse broadening can be achieved with changing power supply voltage,but without changing the delay time of transmission line.The results are verified by experiments.
