ocr: Special Techniques MODELS: L The Bipolar Junction Transistor e There are two commonly used small signal models for the BJT: Cb'c b C Rbb' C H hie gmVbe Rb'e Cb'e gMvDe e e independent Voltage source: 2 - ohm - - 10U The impedance, key is to then assume form a a small Norton internal equivalent a - - 5A 4 2 ohm current source CIEU/R). Many times what actually required is an output voltage for a given input voltage In this case go ahead and apply a current source but ask for vout/vin as an oUr- put quantity.
