Distributed Active Transformer

Distributed active transformer is a circuit topology that allows low-voltage transistors to be used to generate large amounts of RF (radio frequency) power. Its main use has been in making integrated CMOS power amplifier for wireless applications, such as GSM/GPRS cellular phones.

At the time it was introduced, the distributed active transformer gave over an order of magnitude performance improvement over the previous state of the art.

Famous quotes containing the words transformer, distributed and/or active:

    Man, became man through work, who stepped out of the animal kingdom as transformer of the natural into the artificial, who became therefore the magician, man the creator of social reality, will always stay the great magician, will always be Prometheus bringing fire from heaven to earth, will always be Orpheus enthralling nature with his music. Not until humanity itself dies will art die.
    Ernst Fischer (1899–1972)

    Taking food alone tends to make one hard and coarse. Those accustomed to it must lead a Spartan life if they are not to go downhill. Hermits have observed, if for only this reason, a frugal diet. For it is only in company that eating is done justice; food must be divided and distributed if it is to be well received.
    Walter Benjamin (1892–1940)

    So hills and valleys into singing break;
    And though poor stones have neither speech nor tongue,
    While active winds and streams both run and speak,
    Yet stones are deep in admiration.
    Thus praise and prayer here beneath the Sun
    Make lesser mornings when the great are done.
    Henry Vaughan (1622–1695)
