cancel circuit 中文意思是什麼
cancel circuit
解釋
消除電路-
The sample and hold circuit is employed by the bottom plate sampling technique, which could not only cancel the charge injection error but also eliminate the effect of clock feed - through
采樣保持電路設計採用了電容下極板采樣技術，不僅有效地避免了電荷注入效應引起的采樣信號失真，而且消除了時鐘饋通效應的不良影響。 -
To cancel the offset - voltage of the comparator, a switch capacitance circuit is used between the three pre - amplifier stages. the charge pump circuit is used to boost the clock voltage of the switch transistor
採用電荷泵電路提供開關管柵過驅動電壓，帶隙基準電路作為電荷泵穩定電壓的輸入，有利於改善開關電路的性能。 -
The switch power will operate at ccm condition when circuit is set to pwm mode. when pfm mode is selected for the operation mode, the switch power will still operate at pwm condition with the high load, the system will cancel the pwm mode and enter the pfm mode only when the load is drop to a certain threshold to boost the operation efficiency at light load, make the ic has high efficiency within wide load range
選擇pwm模式，開關電源將工作在ccm模式下;選擇pfm模式，在負載較高的情況下，開關電源仍然工作于pwm模式，只有當負載降低到一定程度時，開關電源才退出pwm模式，而按照pfm工作模式操作，跨過一部分時鐘周期，降低頻率相關功耗，以提高輕負載時低效率的問題，使得開關電源在很寬的負載范圍內都具有高效率。
