MOSFETs is simpler and more efficient than the sum of the ic digital logic families pdf gates. RTL gates can be cascaded indefinitely to produce more complex logic functions. MOSFET devices to achieve a high speed with low power dissipation.
Exactly the same as diode logic but can perform at a higher speed. Uses neon bulbs or 3 element neon trigger tubes to perform logic. Performed by semiconductor diodes and small ferrite toroidal cores for moderate speed and moderate power level. Uses thyristors and SCRs to perform logic operations where high current and or high voltages are required. Uses transistors switching between saturated and cutoff states to perform logic. The transistors require carefully controlled parameters. Economical because few other components are needed, but tends to be susceptible to noise because of the lower voltage levels employed.
Often considered to be the father to modern TTL logic. Uses transistors to perform logic but biasing is from constant current sources to prevent saturation and allow extremely fast switching. Has high noise immunity despite fairly low logic levels. Uses the tunnelable q-bits for synthesizng the binary logic bits. This is a transistorless, currentless, junctionless binary logic syntheeis technique. This device has the lighting speed of operation. Electronic logic gates differ significantly from their relay-and-switch equivalents.
Also, there is a fundamental structural difference. It is not possible for current to flow between the output and the input of a semiconductor logic gate. Another important advantage of standardized integrated circuit logic families, such as the 7400 and 4000 families, is that they can be cascaded. This means that the output of one gate can be wired to the inputs of one or several other gates, and so on. Systems with varying degrees of complexity can be built without great concern of the designer for the internal workings of the gates, provided the limitations of each integrated circuit are considered. When gates are cascaded, the total propagation delay is approximately the sum of the individual delays, an effect which can become a problem in high-speed circuits.
Leibniz established that, by using the binary system, the principles of arithmetic and logic could be combined. Boolean algebra in the analysis and design of switching circuits in 1937. 91-1984 and IEC Publication 60617-12. The “distinctive shape” set, based on traditional schematics, is used for simple drawings, and derives from MIL-STD-806 of the 1950s and 1960s.
