Podemos ver o resultado:
Fig. 8
Agora, podemos incluir as redes Zobel na resposta.
Fig. 9
Em vermelho, o ganho desejado, de 31,6x ou 30dB. O traço Ufdbck corresponde a resposta antes da rede RL, formada pelo indutor de 1µH e o resistor de 10Ω.
Resposta interessante, extensa, com desvio de fase irrelevante na faixa audível.
No próximo artigo, resultados adicionais, apresentação da fonte de alimentação, detalhes de projeto de cada estágio e dos ajustes do amplificador. Até lá!
