    • PROBLEM TO BE SOLVED: To provide a full differential amplifier slew rate boosting structure for an amplifier having closed loop gain that is extremely close to an unit or is smaller than the unit.
      SOLUTION: The full differential amplifier slew rate boosting structure used for the amplifier having the closed loop gain being extremely close to the unit or being smaller than the unit connects a first plate of compensating capacitors 50, 52 to internal high-impedance gain nodes 40, 42 as before and drives the second plate of the compensating capacitors 50, 52 by input signals IN+, IN- in a way being different from the conventional one. Voltage that appears by responding to a change in the input signal and crossing the compensating capacitors 50, 52 is clearly smaller than that achieved by using the conventional compensation configuration, where other plates of the compensating capacitor are connected to the earth. Current is hardly required to charge the compensating capacitors 50, 52, thus preventing a slew rate from being restricted by the tail current of an input stage no longer.

    • 要解决的问题:为具有非常接近单元或小于该单元的闭环增益的放大器提供全差分放大器转换速率升压结构。 解决方案:用于具有闭环增益的放大器的全差分放大器转换速率升压结构非常接近单元或小于该单元将补偿电容器50,52的第一板连接到内部高阻抗增益 节点40,42,并且以与现有技术不同的方式通过输入信号IN +,IN-来驱动补偿电容器50,52的第二板。 通过响应于输入信号的变化并与补偿电容器50,52交叉而出现的电压明显小于通过使用常规补偿配置所实现的电压,其中补偿电容器的其它板连接到地球。 对补偿电容器50,52进行充电几乎不需要电流,从而防止压摆率被输入级的尾流不再受到限制。 版权所有(C)2004,JPO&NCIPI
