Adding voltages? What frequencies? What range of voltages? You could do the usual non-inverting or inverting op-amp adder and pick the right part depending on I/O requirements.

Oh nah, it’s just digital arithmetic

"Adder topologies" and I thought https://upload.wikimedia.org/wikipedia/commons/thumb/d/dc/Benny_Trapp_Vipera_berus.jpg/800px-Benny_Trapp_Vipera_berus.jpg

Mostly because my wife identifies snakes for people. And relocates them. (But not adders, 'cause we don't have those here)

Oh! You are doing VLSI stuffs? Like good-'ol MAGIC layout deals?

Yep, been doing VLSI layout work all quarter. Did a whole reg file several weeks ago and some smaller stuff before that

Our final project is an 8 tap FIR filter

Pretty sure adders are poisonous.

The multiplier will be fun.

hahaha yes, yes it will be. though i think its easier to pick a multiplier topology than an adder one :P

I remember hearing about the CLA one (and derivatives).

I think our adder is gonna end up being a Sparse Kogge-Stone tree with Carry increment adders at the bottom in sets of 2

It took a while, but i finally wrapped my head around how to do this damn sparse tree. time to make a schematic
