Abstract: A method and a circuit may have an ability to provide constant currents of a certain set value, the rising and falling edges of which may be shorter than the design minimum on-phase. Essentially, these results may be obtained by keeping an operational amplifier that controls the output power switch in an active state during off-phases of an impulsive drive signal received by the current source circuit in order to maintain the output voltage of the operational amplifier at or just below the voltage to be applied to the control terminal of the output power switch during a successive on-phase of a received drive pulse signal.

Abstract translation: 方法和电路可以具有提供一定设定值的恒定电流的能力，其上升沿和下降沿可能比设计的最小同相时间短。 本质上，这些结果可以通过将运算放大器保持在由电流源电路接收到的脉冲驱动信号的非相位期间处于激活状态而获得，以便将运算放大器的输出电压保持在或 刚好低于在接收的驱动脉冲信号的连续接通相位期间施加到输出功率开关的控制端子的电压。
