hysterisis comparator

[bigheadfish]

Is every MOS device in saturation region? I think some devices are in triode region. Am I right?

 

[kumard35b]

it depends on the operation of the mos transistor in which mode you want to operate..sometimes..in the circuit you need to operate in linear region

 

[pianomania]

if you wanna reduce the quiescent current, you can bias the MOS in linear region , not only constrain on hysteresis comparator

 

[liuyonggen_1]

for a comparator, if the input voltage is changed from low to high or from high to low, some transistors must change their operation state such as from saturation to linear to shut-off.
in my opinion, for hysterisis comparator, some transistors will operate in shut region in turn.
