Current or Voltage Pulse Generator? Spring 2010 Mat 288S Optoelectronic Measurements 2 Current pulse would be preferred, but- stray inductance leads to large voltage spikes min pulse width and max compliance voltage linked inherently high impedance output- reflections circulate Voltage pulse can be faster and larger requires independent measurement of current limited current compliance preferred method for widely varying experimental devices
