    • A high precision clipping regulator circuit includes a first protection diode, a second protection diode, a first offset clamp voltage regulator, and a second offset clamp voltage regulator. The first protection diode is configured to conduct when a voltage potential exceeds a first protection voltage magnitude, and is operable to exhibit variations in the first protection voltage magnitude. The second protection diode is configured to conduct when a voltage potential exceeds a second protection voltage magnitude, and is operable to exhibit variations in the second protection voltage magnitude. The first reference and second voltage regulator circuits are configured to determine when the first and second protection voltages vary and, in response thereto, to vary the first and second variable offset clamp voltages so that a difference in voltage across the protection diodes remains substantially constant.
    • 高精度限幅调节器电路包括第一保护二极管,第二保护二极管,第一偏移钳位电压调节器和第二偏移钳位电压调节器。 第一保护二极管被配置为当电压电势超过第一保护电压幅度时导通,并且可操作以展现第一保护电压幅度的变化。 第二保护二极管被配置为当电压电压超过第二保护电压幅度时导通,并且可操作以显示第二保护电压幅度的变化。 第一参考和第二电压调节器电路被配置为确定第一和第二保护电压何时变化,并且响应于此,改变第一和第二可变偏移钳位电压,使得保护二极管两端的电压差基本保持不变。
