Description
Design a passive linear circuit to generate high voltage spikes from a square wave generator of 10V p-p with a source resistance of 50 , with frequency range less than 5MHz.(eg: 500KHz square wave)
20V
30V
Figure 1: Generated Pulse
Generated voltage spikes must be 25 5V peak. The pulse width at half-amplitude point should be less than 100ns.
Note that your spikes may not have square shape.
Please make sure that the spike duration is much shorther than the input period!
Preliminary Work
Verify your proposed method using SPICE. Assume that fall and rise times of the square wave generator are not zero, but rather 10ns.
Experimental Work
Implement your design. Measure fall and rise times of the square wave generator. Measure the peak voltage you generated.
Compare with your expectations.
Available materials in the lab
You can use toroidal cores, T25-10, T37-7, T38-8, T50-7, to wind transformers. There are standard values of capacitors and resistors available.
