A logic gate is a device that performs a Boolean function, a logical operation performed on one or more binary inputs that produces a single binary output. Depending on the context, the term may refer to an ideal logic gate , one that has, for instance, zero rise time and unlimited fan-out , or it may refer to a non-ideal physical device [ 1 ...
The IETE focuses on advancement of electronics and telecommunication technology. The IETE conducts and sponsors technical meetings, conferences, symposium, and exhibitions all over India, publishes technical [ 1 ] [ 2 ] and research journals [ 3 ] and provides continuing education as well as career advancement opportunities to its members.
Integrated injection logic (IIL, I 2 L, or I2L) is a class of digital circuits built with multiple collector bipolar junction transistors (BJT). [1] When introduced it had speed comparable to TTL yet was almost as low power as CMOS, making it ideal for use in VLSI (and larger) integrated circuits. The gates can be made smaller with this logic ...
Propagation delay timing diagram of a NOT gate A full adder has an overall gate delay of 3 logic gates from the inputs A and B to the carry output C out shown in red.. Logic gates can have a gate delay ranging from picoseconds to more than 10 nanoseconds, depending on the technology being used. [1]
Digital electronics is a field of electronics involving the study of digital signals and the engineering of devices that use or produce them. This is in contrast to analog electronics which work primarily with analog signals. Despite the name, digital electronics designs include important analog design considerations.
The AND gate is a basic digital logic gate that implements the logical conjunction (∧) from mathematical logic – AND gates behave according to their truth table. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If any of the inputs to the AND gate are not HIGH, a LOW (0) is outputted.
A transmission gate (TG) is an analog gate similar to a relay that can conduct in both directions or block by a control signal with almost any voltage potential. [1] It is a CMOS -based switch, in which PMOS passes a strong 1 but poor 0, and NMOS passes strong 0 but poor 1.
Every CPL gate has two output wires, both the positive signal and the complementary signal, eliminating the need for inverters. [ 9 ] [ 10 ] [ 11 ] Complementary pass transistor logic or "Differential pass transistor logic" refers to a logic family which is designed for certain advantage.
