slide5

Schéma de simulation APD

Tau = 50 ns , G = 1

Rf = 600kW, Cf = 450fF

slide6

Adm vs Vmc

Gdc = 67 dB

Marge de phase = 75°

slide8

Simulations Transitoires

Pulse rapide

(Step de 1V sur 50fF, rise time qqns)

Pulse lent

(triangle rise time 5ns et fall time 160ns)

51 mV, 65ns

51ns , +- 85mV

slide9

Simulations Transitoires

40 mV, 100ns

72.6 mV, 114ns

71.8 mV, 115ns

Pulse lent

(rise time 5ns et tau 40ns)

PA en Single Ended 102ns

slide10

Bruit :

  • Cd=80pF
  • Cf=450fF
  • Rf=600kW
  • Tau = 50ns
  • ENC = 3000e-
  • Tau =20ns
  • ENC = 5000e-
  • Vmc out vs Vcons :
  • DVmc out / DVcons = 0.98
