A CMOS voltage comparator with internal positive current feedback to achieve a predetermined hysteresis. The voltage level at which the switching occurs is precisely settable. Hysteresis is introduced such that when the set voltage level is exceeded, the output switches quickly and will remain in ...
hysteresis with “mult” as a sweeping variable We can see, that the bigger the ratio between M15 and M1 is, greater is the hysteresis. To graphically represent the hysteresis, normally the sweeping input voltage is plotted versus the output. This shows better the called bistable characteristic....
