![]() ![]() ![]() This process, loosely described as Moore’s law, has kept the chip industry humming for a half-century, but it’s getting harder. That means making already atomic-sized features even smaller. Doing so requires some of the most complex, expensive manufacturing equipment on the planet, and the development of even more creative ways to improve fundamental aspects of chip construction. In 2025, Gartner expects chip manufacturers to generate roughly $5 billion in revenue from the new technology, up from nothing last year.Ĭhip companies must deliver substantially more computing horsepower every year to get to a version of the future that’s been promised by the tech titans. Modern chips can have upwards of 30 billion transistors on a single device, and in some cases tens of billions more. This next-generation design is called “gate-all-around.” With new materials, and redesigned manufacturing tools that cost tens of millions each, the new gates accomplish one thing: They more tightly control the flow of electricity received by each transistor. ![]() This leap must occur to realize anything close to the computing requirements demanded by the ideas behind the metaverse, to produce AI that isn’t a joke, to make truly self-driving cars or even make apps load faster. Intel, Samsung and TSMC are racing to achieve a generational leap in transistor technology. I simply chose the resistors based on what I had available at the time.Īdditionally if the role of the transistors in the circuit does not make sense to you please look at my earlier post ( TRANSISTOR CRASH COURSE ) that explains the functioning of transistors and their roles in circuits.A once-in-a-decade shift is underway involving one of the most elemental building blocks of computer chips, and it has the potential to reshuffle the pecking order of chip giants for years to come. Just note the selection of resistor sizes are not cast in concrete, just pick a resistance high enough so your transistor does not get fried based on your power supply size (in my case a 9 Volt battery). The circuit thus represents the OR function. Because the 2 transistors are placed in parallel the circuit can be completed by pressing either the A or B button (or both). So by pushing the buttons in accordance to the OR state table the corresponding outputs can be recreated. 3 resistors (1 x 10k Ohm and 2 x 660 Ohm resistors will do).Because the 2 transistors are placed in series the circuit can only be completed when both button A and B are pressed, and thus the AND function is implemented. So by pushing the buttons in accordance to the AND state table above the outputs can be recreated. (I have constructed both gates on a Adafruit Perma-Proto board shown in the picture below). We will also look at the NOR and XOR functions and gates in detail at a later time).īelow is the state table for the OR function with inputs A and B as well as the resulting output: A Additionally the XOR function will give a positive “on” output only when A or B are “on” but NOT when both are “on”. (Just note the NOR function requires neither A or B to be in an “on” state to give a positive “on” result. We will look at the NAND function and gate in detail at a later time).īelow is the state table for the AND function with input s A and B as well as the resulting output: AĪn OR function requires either A or B (or both) to be in an “on” state to give a positive “on” result. (Just note the NAND function will give a positive “on” output when A and B are NOT both “on”. Logic gates are physical circuits that implements boolean functions, so to start let us look at the boolean AND and OR functions.įor all the examples below let us assume that we have 2 inputs: A and B, and that A and B both have 2 possible states: on or off, 1 or 0 in binary terms.Īn AND function requires both A and B to be in an “on” state to give a positive “on” result. I will be discussing the 2 most basic logic gates today, an AND gate and an OR gate. The basis of building any logic circuit (even one as complex as a computer) comes down to logic gates.
