Hi,
Could some one help me to realize a simple circuit to detect a node voltage which running out of some range?
In my circuit, there is an output node of an OP, when in normal operation, it's about 1.8V~2.0 at all corners, but if the OP's feedback node is shorted to some voltage, this node will be out of this range and falls into ~VDD or ~GND.
Is there simple circuit to indicate this internal voltage is out of 1.8V~2.0V?
Thanks to everyone.
