摘要： PROBLEM TO BE SOLVED: To provide a single stage balanced voltage amplifier to achieve a high signal gain while holding an output impedance low.
SOLUTION: The balanced voltage amplifier includes a single stage having three pairs of vacuum tube triodes for amplifying two input signals (+ Input and - Input), and generating two output signals (+ Output and - Output). The balanced voltage amplifier provides a high voltage gain, wide bandwidth and low output impedance. A local feedback may be provided between the outputs and a second pair of the vacuum tube triodes. An overall feedback may be provided between the outputs and a first pair of the vacuum tube triodes. With the use of the local or overall feedback, further broadening the bandwidth and lowering the output impedance improve the overall balancing.

解决方案：平衡电压放大器包括一个单级，具有三对用于放大两个输入信号（+输入和 - 输入）的真空管三极管，并产生两个输出信号（+输出和 - 输出）。平衡电压放大器提供高电压增益，宽带宽和低输出阻抗。可以在输出端和第二对真空管三极管之间提供局部反馈。可以在输出和第一对真空管三极管之间提供总体反馈。通过使用本地或整体反馈，进一步拓宽带宽和降低输出阻抗，提高整体平衡。版权所有（C）2008，JPO＆INPIT
