• Parameters of CE configurations are as follows
• Input impedance$(h_{ie})$
• Output admittance$(h_{oe})$
• Reverse voltage gain$(h_{re})$
• Forward current gain$(h_{fe})$
• Input impedance(hie): It is the ratio of change in input or base-emitter voltage$(V_{EB})$ to change in base current $(I_B)$ at a constant output or collector-emitter voltage$(V_{CE})$ $$h_ie=\frac{∆V_{EB}}{∆I_B} , V_{CE}=constant$$
  • It is determined from …
