The most common situation for a general-purpose analog computer is to add two voltages (referenced to ground); this can be accomplished roughly with a resistor network, but a better design exploits an operational amplifier.
In this work, a novel ultrasonic actuator, which exploits a displacement amplifier vibrating in a flexural mode, is proposed.
A narrow band CMOS low noise amplifier (LNA) achieving high third-order input intercept point (IIP3) is proposed exploiting a non-linearity cancelation technique at RF frequency.
It did so by exploiting a loophole.
But exploiting a brand name is tricky.
A new device, the Thin-Film Trans-Capacitor, is presented and used to build the discrete-time amplifier, while the continuous time amplifier exploits a simple traditional architecture to improve yield.
Both versions exploit an inherent advantage of Raman amplifiers: they disrupt the data carried by light much less than other methods of amplification do, thus eliminating costly equipment used to correct the signals.
Designed for radioastronomy applications, this amplifier exploits a common-drain configuration as input stage and a common-source inductive degeneration topology as output stage.
This method exploits a feedback mechanism between the amplifier output and the modulator, whose goal is to make the constellation actually transmitted as close as possible to the ideal constellation.
Chelsea must exploit an opportunity.
For the former, we use a power meter and an optical spectrum analyser (ANDO AQ6317), while for the latter we exploit a high-speed photodetector (NewFocus 1554-B, 12 GHz) followed by an electronic amplifier, combined with an electrical spectrum analyser (Anritsu, MS2667C, 30 GHz) or an oscilloscope (Tektronix CSA7404, 4 GHz, 20 GSamples/s).
