| 英文摘要 | In a first aspect of the invention, a driven element is driven by a static driving element coupled in series with a switching element. The static driving element sets the driving current value. In a second aspect, a plurality of driven elements are driven by respective driving elements, which in turn are driven by respective pre-stage circuits, using a control voltage supplied by a single control-voltage generating circuit. Resistors inserted between the driving elements and pre-stage circuits limit transient current flow to a value within the output capability of the control-voltage generating circuit. In a third aspect, the pre-stage circuits have constant-current output characteristics, and the control-voltage generating circuit is designed to provide the necessary transient current, even when all driven elements are driven simultaneously. |
