A Class B push–pull output driver using a pair of complementary PNP and NPN bipolar junction transistors configured as emitter followers. A push–pull amplifier is a type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load. This kind of amplifier can enhance ...
The diamond buffer or diamond follower is a four-transistor, two-stage, push-pull, translinear emitter follower, or less commonly source follower, in which the input transistors are folded, or placed upside-down with respect to the output transistors. [3]

Push–pull strategy, in logistics, supply chain management and marketing; Push–pull workout, a type of weight-lifting routine
For alkaline buffers, a strong base such as sodium hydroxide may be added. Alternatively, a buffer mixture can be made from a mixture of an acid and its conjugate base. For example, an acetate buffer can be made from a mixture of acetic acid and sodium acetate. Similarly, an alkaline buffer can be made from a mixture of the base and its ...
A push-pull configuration also helps to stabilize the double bond because the carbon-carbon bond has considerably less double bond character. For instance, cyclobutadiene is a very unstable molecule but with both olefinic bonds in push-pull configuration (two ester substituents and two tertiary amine substituents) the molecule is stable indeed.
I3C uses open-drain mode when necessary for compatibility, but switches to push-pull outputs whenever possible, and includes protocol changes to make it possible more often than in I²C. SCL is a conventional digital clock signal, driven with a push-pull output by the
Good's buffers (also Good buffers) are twenty buffering agents for biochemical and biological research selected and described by Norman Good and colleagues during 1966–1980. [ 1 ] [ 2 ] [ 3 ] Most of the buffers were new zwitterionic compounds prepared and tested by Good and coworkers for the first time, though some ( MES , ADA , BES , Bicine ...
Many other buffers have been proposed, e.g. lithium borate, which is rarely used, based on Pubmed citations (LB), isoelectric histidine, pK matched goods buffers, etc.; in most cases the purported rationale is lower current (less heat) matched ion mobilities, which leads to longer buffer life. Borate is problematic; Borate can polymerize, or ...
