Chapter 4 Calculating the Logical Effort of Gates

bwrcs.eecs.berkeley.edu

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.

8. TIME DEPENDENT BEHAVIOUR: CREEP

d) Silicon nitride melts/dissociates at ~1850°C=2123 K and is known to creep in advanced heat engine applications of 1300°C=1573 K. The homologous temperature is 1573 2123 = 0.74 which is greater than 0.5 so this is consistent with the definition of creep. Conceptually a creep test is rather simple: Apply a force to a test specimen and
