Implementing inverse circuit for binary nos

[venkat3271]

Hey,
Can anybody give the circuit/concept for implementing the inverse circuit(ie if v give x as an input , the circuit should give 1/x). ...For binary nos(digital implementation) ....


Thanks in advance....

Inverse circuit...

This sort of thing is often done with a lookup table. You precompute the answers for the desired range of inputs and then pre-load them into a BlockRam within the FPGA.

True, or You can use "dividers", if they're supported within Your device and developing software.

I think using some look uptables with predefined values would be a better way of doing it rather than giong in for some complete sequential or combinational block......

Inverse circuit...

Some context on the application is needed if you can't find a schematic or
parts list. Zeners are usually used for either protection or as a
reference. What is it connected to?

Hi everyone, I am repairing an industrial PSU and there is a few glass
types zener diode on board and I found one which is shorted but the
problem with these small glass type zener is that it is only marked with
the numeric "123" and nothing more than that so how do I know what is the
zener voltage of this diode?

Thanks
