amplifierElectronic device that increases the strength of a signal, such as a radio signal. The ratio of output signal strength to input signal strength is called the gain of the amplifier. As well as achieving high gain, an amplifier should be free from distortion and able to operate over a range of frequencies. Practical amplifiers are usually complex circuits, although simple amplifiers can be built from single transistors or valves. How to thank TFD for its existence?

| Tokyo, Japan, Feb 15, 2007 - (JCN) - Onkyo announced the release
of its "BR-NX10(S)" CD/HDD tuner amplifier and the
"D-NX10" 2-way speaker system). The impedance multiplication concept with a positive feedback
buffer amplifier was analyzed and utilized in a bootstrap PV
transimpedance amplifier to measure photocurrent of a 200 [omega] shunt
resistance photodiode with a maximum signal gain of [10. (NYSE:TRW), a world leader in advanced semiconductors, has
developed a highly efficient microwave power amplifier chip that
delivers world record levels of power per unit of semiconductor area for
integrated circuits operating at more than 20 billion cycles per second
(20 GHz). |
