Chapter 4 Calculating the Logical Effort of Gates

4.3 Calculating logical effort Definition 4.2 provides a convenient method for calculating the logical effort of a logic gate. We have but to design a gate that has the same current drive character-istics as a reference inverter, calculate the input capacitances of each signal, and apply Equation 4.1 to obtain the logical effort.

of arbitrary digital gates such as NOR, NAND and XOR. The focus will be on combina-tional logic (or non-regenerative) circuits that have the property that at any point in time, the output of the circuit is related to its current input signals by some Boolean expression (assuming that the transients through the logic gates have settled).

SEMICONDUCTOR MEMORIES

The read-out of the 1T DRAM cell is destructive; read and refresh operations are necessary for correct operation. Unlike 3T cell, 1T cell requires presence of an extra capacitance that must be explicitly included in the design. When writing a “1” into a DRAM cell, a threshold voltage is lost.

etch rate. Silicon dioxide or silicon nitride is usually used as a masking material against HNA. As the reaction takes place, the material is removed laterally at a rate similar to the speed of etching downward. This lateral and downward etching process takes places even with isotropic dry etching which is described in the dry etch section.

the etch rates of other materials that will be exposed to the etch, such as masking films and underlying layers, enables an etch process to be chosen for good selectivity (high ratio of etch rate of the target material to etch rate of the other material)—if one exists. While several large literature-review compilations

is very narrow. If the application calls for a black etch, consider using an oxidizer after engraving. Oxidizers are used most commonly if the aluminum has a protective coating (urethane, clear coat, clear anodized) covering the area that is not engraved. Deep metal engraving on aluminum can be done using multiple passes.
