Draw and discuss power failure detection circuit interrupt NMI.
The non-maskable interrupt (NMI) is an edge-triggered input which requests can interrupt upon the positive-edge. Then after a positive edge, the NMI pin should remain logic 1 till it is recognized through the microprocessor.
The NMI input is frequently used for parity errors and other main system faults, like power failures. Power failure is simply detected through monitoring the AC power line and causing an NMI interrupt when AC power drops out. Within response to that type of interrupt, the microprocessor stores all of the internal register into a battery backed-up-memory or an EEPROM. The below figure demonstrates a power failure detection circuit which provides a logic 1 to the NMI input while ever AC power is interrupted.

Now you have to digitally implement this circuit. Compute a difference equation which if you implement will behave exactly like this circuit.
Q. A silicon diode is forward-biased with V = 0.5 V at a temperature of 293 K. If the diode current is 10 mA, calculate the saturation current of the diode.
