The differential outputs (3, 4) of the first stage are applied to the inputs of a second differential amplifier stage (32, 35) which is of the same design as the first stage. A hysteresis element (31) is added to the current mirror load (30, 34) of the second stage and is driven...
Implementation of adjusting the hysteresis threshold must involve extra effort to design the comparator circuit with fast online tuning capability of the hysteresis threshold.

I have also attempted to enable and disable hysteresis with no change in behavior. Signal captures and a sample project are both attached for clarity. Thanks, Karl Solved! Go to Solution. Topics: PSoC 5LP screenshot.png 78 KB Solo_7.cywrk.Archive01.zip screenshot_pulse.png 102 KB...
During the reset cycle of differential comparator circuit 100, the RESET signal is high. FETs 120 and 128 therefore act as closed switches, shorting the output nodes 105 and 109 to VDD. Periodic resetting of differential comparator circuit 100 is beneficial because of the hysteresis introduced into...
For an inverting configured comparator, hysteresis can be added with a three resistor network and positive feedback. When input voltage (VIN) at the inverting node is less than non-inverting node (VT), the output is high. The equivalent circuit for the three resistor network is R1 in ...
Design and application of the novel low-threshold comparator using hysteresis Comparators using hysteresis were widely used in IC design. The paper first introduces the design of the conventional comparator using hysteresis and its d... X Guo,X Lai,Y Li,... - International Conference on Asic 被...

This reset function prevents hysteresis effects and during the reset phase clears any signal excursion which may still be present at the output so that in the next clock pulse cycle the output signal does not depend on the past history. During an amplification phase which immediately follows the...
