摘要
设计了一种低功耗的张弛振荡器,该设计动态地改变了振荡器中比较器的电流,使其只在斜坡电压接近阈值电压时才增大,因此既减小了比较器的延迟,也维持了一个较低的平均电流,保证稳定性的同时做到了低功耗。一个设计实例显示,使用这个技术减小了81.8%的功耗,而维持了相同的频率稳定性。
A low-power relaxation oscillator is presented. The current of the comparator in the oscillator is adjusted dynamically in this design, i.e. it is increased when the slope voltage approaches the threshold voltage. It shortens the comparator delay as well as maintains low average current, guarantees the stability and achieves low power consumption. A prototype indicates the power consumption of 81.8%is saved, and the same frequency stability is maintained.
