From light to logic: First complete logic gate achieved in soft material using light alone

Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of ...

VHDL 101 – From Logic Gates to Adders

VHDL is all about creating logic. As a descriptive language, all the HDL languages bring something unique to programming – making true parallel logic circuit. As we take baby steps into VHDL, we will ...

Using isolated ADCs and an XNOR logic gate as a multiplier to measure active power

Multiplying two analog signals involves the use of analog multipliers, usually implemented by using log and antilog circuit blocks or the Gilbert cell. Today, the most common technique used to ...
