Electricity consumption only reduction the digital level shifter which obstructs the transmission of untruth

摘要

The digital level shift circuit (70), like the high tension MOS element the element where level it shifts (82, 84, 92 and 94) it includes, at the same time and the feedback circuit (102) it is possible to include. As for the element which aforementioned level is shifted it is turned is turned on because it can point to output transition, at the same time as for the aforementioned feedback circuit, it acquires the verification signal which shows the fact that you can do return namely the aforementioned transition. Responding to this, it is possible the element which aforementioned level is shifted to turning & to turn off the aforementioned feedback circuit, because of this to reduce electricity consumption.
