Patent ID: 8149039

Claim:
A pulse generator circuit, comprising: a voltage source; a load; a transmission line operably connected between said voltage source and said load, said transmission line have a length and a characteristic impedance; an N-type field effect transistor having a gate terminal, a drain terminal, and a source terminal, said drain terminal of said N-type field effect transistor being operably connected to said transmission line and said source terminal of said N-type field effect transistor being directly connected to ground; and a trigger circuit operably connected to said gate terminal of said N-type field effect transistor, said trigger circuit providing an input pulse to said gate terminal, said N-type field effect transistor being driven to a linear regime when said input pulse is provided to said gate terminal, said transmission line discharging an output pulse across said load resistor when said N-type field effect transistor operates in the linear regime; said output pulse having a full-width-half-magnitude pulse width in the range of about 6.0 picoseconds to about 10.0 picoseconds; wherein said transmission line, said N-type field effect transistor, and said trigger circuit are located on a common semiconductor substrate.
