No, it won't. The problem is that the efficiencies of analog multiplications get swamped by the need to digitize the outputs at some point. Converting back to digital with many bits of precision is a slow, energy consuming process. If you want to take a single analog voltage, and convert it to 16 bits, for example, at 80 million samples per second, the LTC2163[1,2] will do it, but it's a $120 chip, and consumes 108 mWatt to do it. Lower resolutions, and slower speeds cost less, but still that's the major problem you encounter. [1] https://www.digikey.com/en/products/detail/analog-devices-in...
