| 摘要 |
<p>A pulse amplifier (Q7, Q8) suitable for use as the pulse current supply circuit (9) in a semiconductor driving device, which circuit cuts off a pulse top side portion and a pulse base side portion of an input pulse with respect to a mesial point of the input pulse to obtain an output pulse having a desired pulse amplitude in response to a control signal, without varying a pulse width. <IMAGE></p> |
