| Abstract: | A high fidelity headphone amplifier for low impedance headphone is designed,which uses GG (Grounded Grid) circuit as the input entry,and WCF circuit as the output entry.Based on the analysis of vacuum tube slight variation equivalent circuit,the primary parameters of the input and output entry are calculated,and the open-loop and closed-loop parameters of the whole amplifier are also analyzed.In the end,the function of the amplifier is explained through impersonal-measurement and subjective evaluations. |
