Domino logic is a CMOS -based evolution of dynamic logic techniques consisting of a dynamic logic gate cascaded into a static CMOS inverter. [2] The term derives from the fact that in domino logic, each stage ripples the next stage for evaluation, similar to dominoes falling one after the other. Domino logic contrasts with other solutions to ...
The hex inverter is an integrated circuit that contains six inverters. For example, the 7404 TTL chip which has 14 pins and the 4049 CMOS chip which has 16 pins, 2 of which are used for power/referencing, and 12 of which are used by the inputs and outputs of the six inverters (the 4049 has 2 pins with no connection).
CMOS inverter (a NOT logic gate). Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss", / s iː m ɑː s /, /-ɒ s /) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.

v. t. e. Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory; data is lost when power is removed. The term static differentiates SRAM from DRAM (dynamic random-access memory): SRAM will hold its data permanently in the ...
A CMOS inverter circuit. By definition, the logical effort g of an inverter is 1. If the inverter drives an equivalent inverter, the electrical effort h is also 1. The parasitic delay p of an inverter is also 1 (this can be found by considering the Elmore delay model of the inverter).
In a digital circuit, the noise margin is the amount by which the signal exceeds the threshold for a proper '0' (logic low) or '1' (logic high). For example, a digital circuit might be designed to swing between 0.0 and 1.2 volts, with anything below 0.2 volts considered a '0', and anything above 1.0 volts considered a '1'. Then the noise margin ...
T and − T are the switching thresholds, and M and − M are the output voltage levels. In electronics, a Schmitt trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier. It is an active circuit which converts an analog input signal to a ...
A schematic of a simple 3-inverter ring oscillator whose output frequency is 1/ (6×inverter delay). A ring oscillator is a device composed of an odd number of NOT gates in a ring, whose output oscillates between two voltage levels, representing true and false. The NOT gates, or inverters, are attached in a chain and the output of the last ...
