The circuit was designed to create a handy logic probe that can show off the logic states for high, low and pulsing outputs with the use of CMOS 4001 integrated circuit. Logic Probe – a handheld probe ...

Addition forms the basic structure for many processing operations like counting, multiplication, filtering etc. Adder circuits that add two binary numbers are of great interest for many designers. The ...

Current-Mode Logic (CML) and low-power Complementary Metal-Oxide-Semiconductor (CMOS) technology continue to drive significant advances in digital circuit design, particularly in high-speed and energy ...

High performance microprocessor units require high performance adders and other arithmetic units. Modern microprocessors are however 32-bits or 64-bits as that is the minimum required for floating ...

Density and speed of IC’s have increased exponentially for several decades, following a trend described by Moore’s Law. While it is accepted that this exponential improvement trend will end, it is ...

Fig 1. A typical CMOS input circuit comprises a “P” and “N” transistor. One is fully “on” for logic high, and the other is “on” for a logic low. Fig 2. When a CMOS input pin is at logic high or low ...

In this column, we consider the evolution of complementary metal-oxide semiconductor (CMOS) technology, which was invented by Frank Wanlass in 1963. In this column, we consider the evolution of ...
