delay programming voltage. The fast switching and ramp
linearity permits 1ns accuracy and 100ps repeatability.
Figure 13, a high speed expansion of the current source
turn-on, details the clean switching. Q4 goes off within 2ns
of the trigger input (Trace A) dropping low, enabling the
current source (Q2’s emitter is Trace C). Concurrently, the
1000pF capacitor’s ramp (Trace B) begins. The LT1394’s
output (Trace D) drops low about 7ns later, returning high
after crossing (in this case) a relatively low programming
voltage. Figure 14 juxtaposes the waveforms differently,
permitting enhanced study of circuit timing. Switching
begins with the input trigger falling low (Trace A). The ramp
(Trace C) begins 3ns after the current source turns on (Q2
emitter is Trace D). The output pulse (Trace B) begins
about 4ns later.
To calibrate this circuit apply a trigger input and 3V to the
programming input. Adjust the 100
trim for a 300ns
width at the LT1394’s output.
