I need help to identify the negative feedback loop in a hysteresis comparator

If you look at a half circuit analysis, you're removing the negative feedback created by M2. So you must look at both halves of the circuit together to understand the feedback path. This is simply a ...

I need help to identify the negative feedback loop in a hysteresis comparator

Referring to feedback in this circuit may be confusing because the feedback is in the load of the differential pair. In contrast, textbook feedback examples have feedback from output to input. First, ...

I need help to identify the negative feedback loop in a hysteresis comparator

Suppose the comparator front end is at balance. You can simplify it as the drains both being connected to fixed voltages and the sources connected together to a current sink. At balance each ...
