design ideas Simple, Fast Pulse Source Outpaces Expensive Lab
Equipment
Mitchell Lee A source of fast pulse edges, simulating a step function, is often useful in making lab
measurements of one kind or another. For example, it is possible to evaluate the rise
time of RG-58/U or other coaxial cables using lengths of only 10 to 20 feet if an edge
rate on the order of 1nsвЂ“2ns is available. The ubiquitous HP8012B pulse generator,
a workhorse in many labs, falls short at 5ns, and is not quite fast enough for the
task at hand. The gate drive output rise and fall times of certain switching regulator
controllers are faster than 2ns, making such devices potentially ideal pulse sources.
Figure 1 shows a simple implementation
using an LTC3803 constant frequency
flyback controller. The controller selfclocks at 200kHz; applying a sample
of the output to the SENSE pin causes
the device to operate at its minimum
duty cycle, producing a 300ns output
pulse width. Supply bypassing is important, as the output delivers upwards
of 180m A into a 50О© load. The 10Вµ F
bypass and 200О© decoupling components minimize pulse top aberration
without compromising droop. prime importance, back termination (as
shown) is recommended to suppress triple
transit echos by absorbing reflections from
cabling and the far-end termination. Back
termination is also useful when driving …
