无

采样设备单一电压负电压模拟数字转换器驱动电路

▸创新点1：单一电压供电技术，通过内部电路设计实现在单电源电压下完成信号采样，避免了传统设计中需要双电源供电的复杂性，显著降低了系统功耗和成本。

▸创新点2：无需外部负电压支持，采用创新的电平移位和采样保持电路结构，使得输入信号电压可以低于负电源电压而无需额外负电源或衰减电阻，简化了外围电路设计。

▸创新点3：简化驱动电路设计，通过优化采样开关和控制逻辑，减少了驱动电路的复杂性和功耗，提高了系统的整体效率和可靠性。

▸创新点4：适用于模数转换器（ADC）等多种电路，该技术不仅限于特定应用，还可广泛应用于需要宽输入电压范围采样的其他电路系统中，具有较高的通用性和扩展性。
