Netlist line

electronics.bjt bjt ('Nb', 'Nc', 'Ne'): Is=1e-12; betaR=10.0; betaF=200.0; Vt=0.026; mu=1.0; Rb=20.0; Rc=0.1; Re=0.1;

Example

>>> # Import dictionary
>>> from pyphs.dictionary import electronics
>>> # Define component label
>>> label = 'bjt'
>>> # Define component nodes
>>> nodes = ('Nb', 'Nc', 'Ne')
>>> # Define component parameters
>>> parameters = {'Is': 1e-12,     # Reverse saturation current (A)
...               'betaR': 10.0,   # Reverse common emitter current gain in [0, 20] (d.u.)
...               'betaF': 200.0,  # Forward common emitter current gain in [20, 500] (d.u.)
...               'Vt': 0.026,     # Thermal voltage at room temperature (V)
...               'mu': 1.0,       # Ideality factor in [1, 2] (d.u.)
...               'Rb': 20.0,      # Zero bias base resistance (Ohms)
...               'Rc': 0.1,       # Collector resistance (Ohms)
...               'Re': 0.1,       # Emitter resistance (Ohms)
...              }
>>> # Instanciate component
>>> component = electronics.Bjt(label, nodes, **parameters)
