【摘要】 过去运用正向体偏压技术设计的低功耗电路存在一个缺陷,即晶体管截止后的漏电流随着阈值电压的减小而迅速增大,增加了电路的静态功耗。本文采用了自适应体偏压技术弥补了这个缺陷,改进了低压低功耗电路的设计技术。同时介绍了用这种技术设计的低压施密特触发器,工作电压为1.4V,延迟宽度为0.6V,功耗仅为7.3540uW。更多还原

【Abstract】 In the past,the forward body-biased technique has been used for low power circuits design.However,a shortcoming exists in the method.When the transistor is turned-off,the leakage current increases owing to reduced threshold voltage.In this paper,a adaptive body-biased technique is proposed to overcome the shortcoming which is intrinsic in the body-biased MOSFET.Low power circuits design techniques are improved.Schmitt trigger which is designed with the technique is introduced at last.At a 1.4 V power supply,the hysteresis width is 0.6V,but power consumption is only 7.3540uW.更多还原
