+ | __**Delta-like input current spike**__ | ||
+ | |||
+ | Use an **ipulse** current source with a trapezoidal shape | ||
+ | Let ''w'' be rise time, pulse width and fall time of the current pulse (e.g. 1ns), then set i2 to | ||
+ | |||
+ | <code> | ||
+ | Qin*1.6e-19/(2*w) | ||
+ | </code> | ||
+ | |||
+ | with ''Qin'' expressed as the **number of electrons**. | ||
+ | |||
+ | |||
+ | |||
+ | \\ | ||
+ | __**Equivalent Noise Charge (ENC)**__ | ||
+ | |||
+ | |||
+ | |||
+ | \\ | ||
+ | __**Time over threshold (ToT)**__ | ||
+ | |||
+ | Define a ''ToT'' output variable in ADE L with the usage of the ''cross()'' OCEAN function, | ||
+ | |||
+ | |||
+ | <code> | ||
+ | (cross(VT("/Vout_comp") 0.3 1 "falling" nil nil) - cross(VT("/Vout_comp") 0.3 1 "rising" nil nil)) | ||
+ | </code> | ||
