Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Cascode Magnitude Compare Circuit
This circuit provides a magnitude compare of binary words and reduces the
number of devices and required power used in other known compare circuits.
The basic bit compare cell 10 (Fig. 1) generates a magnitude compare
function on the corresponding individual bits Ai and Bi of multibit, e.g., N bits,
signals A and B. Bits Ai and Bi and their NOT or complementary counterparts Ai
and Bi are fed to respective input terminals 11-14, 14' of the cascode current
switch cell 10, as shown. By way of example, cell 10 is configured with NPN
bipolar devices T1-T6, and the voltage at the input terminals 11-14, 14' is at a
more positive level when representing a logical 1 than when it represents a
For the equality condition Ai = Bi = 1, the current i supplied through resistor
R4 switched through T1 as Ai is higher than Ai. Similarly, the collector current of
T1 flows through T4 and hence R3 and produces a low voltage at the equality
output terminal 15 which represents a match or true or DOWN state and an
active status. No current flows through R1 and R2 and therefore the Ai > Bi
output terminal 16 and the Bi > Ai output terminal 17 are in UP states, indicating
an inactive status.
For the equality condition Ai = Bi = O, the output terminals 15-16 remain in
their respective aforementioned states and status. However, the current path is
now through T2 and T6.
It can be likewise shown that for the unequal condition Ai > Bi, the current
