The curveprocess program

The curveprocess program extracts and calculates DUT parameters from the curve data in pypsucurvetrace files:

  • Gate/grid voltage \(V_{\rm G}\) or base current \(I_{\rm B}\) corresponding to a given operating point (\(U_1\), \(I_1\))

  • Transconductance \(g_{\rm m}\) or current gain \(h_{\rm fe}\) at a given operating point (\(U_1\), \(I_1\)):

\[g_{\rm m} = ∂I_1/∂U_2 \textrm{ or } h_{\rm fe} = ∂I_1/∂I_2\]

  • Output conductance (or output transresistance) \(g_{\rm o}\) at a given operating point (\(U_1\), \(I_1\)):

\[g_{\rm o} = ∂I_1/∂U_1\]
