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.

Low Power Dissipation Push Pull Driver
The above circuit, which represents the low-power push-pull driver circuit,
consists of a push-pull type of driver with an active terminator and a receiver
circuit at the end of the line.
The main objective of this circuit is to combine two opposite requirements of
having high performance incident NETS and low power dissipation. Both
requirements are obtained in the circuit with a DC power dissipation that could be
as low as 6 milliwatts. Other important features are: 1. Very low delta I noise
because of the slow output transitions without affecting appreciably the high
internal drive speed. 2. Three state capability, allowing collector DOT of many
drivers. 3. Very low (can be assumed zero) voltage drop on the transmission line
because of the absence of terminators. 4. Protection against the electrostatic
discharges because of the active terminators. 5. Low driver output impedance in
both states. 6. Low-power supply requirements as compared to similar type of
drivers. 7. Incidence performance with low Zo lines.
The circuit operation is as follows: We first define the active terminator
clamped up-level and down-level voltages as clamped up level = (+V1 + 0.8)
volts, and clamped down level = +V1 -0.8 -0.8 = (+V1-1.6) volts.
For the input VIN at an up level, T1 is off, T4 is on, T2 is off, T3 is off, and T5
is on, holding the output at a down level of +VCE5 or at a clamped voltage of the
diode terminators in case of negative re...
