During the time period of the output pulse, the first transistor is in a non-conducting state and the voltage level at the bootstrap point is high, imposing a stress upon the first transistor. A discharging circuit consisting of at least one transistor is coupled to the bootstrap point in order to reduce the voltage level at the output pulse period. | 02-26-2009 |
