Abstract
An AD 8099 Operational Amplifier was simulated in LT Spice in both one-stage and two-stage configurations for use in amplifying pulses coming from a cosmic-ray muon detector. The simulation showed that the AD 8099 is highly effective in amplifying pulses down to the 100 nV input range, with amplifications of 10-20 times in the case of the one-stage amplifier and 150-400 times in the case of the two-stage amplifier. The simulation also showed reasonable levels of pulse widening down to the 100 nV input range, with the pulse widening by no more than twice its original width in the one-stage configuration and no more than three times its original width in the two-stage configuration. At input pulse voltages below 100 nV the performance of the AD 8099 begins to degrade. Offset voltages were found to be stable for all pulse shapes and input voltages investigated in both one-stage and two-stage configurations.
