Pspice Simulations

Intro. To Capture/PSpice

Simulation of EST

Simulation of Existing Test Beam

capture and pspice
Capture and PSpice
  • can create schematics for analog or mixed signal designs, PCB layout
  • PSpice can simulate analog designs
    • PSpice libraries contain over 11,000 parts
    • can download PSpice models directly from manufacturer’s web sites
pspice simulation output
PSpice Simulation Output
  • PSpice can perform DC, AC, transient analyses
  • You can place “probes” at any part of the circuit
  • Output can be written to ASCII file for further analysis

est ideas
NOMINAL:

4 identical current pulses

I(t) = Io(1-t/td)

Io = 100 nA

td = 400 ns

NON-NOMINAL:

Due to potential difference, gaps between plates of capacitors change

1 pulse is longer than the other 3

hec electronics chain1
HEC Electronics Chain
  • PSpice model based upon schematic and electronic parameters presented in HEC Note 109
  • rough circuit design complete
    • Need more info. about Kapton cable spec’s
    • May replace Laplace equations with equivalent circuitry

  • calibration pulse measured on Strip Line (SL)
