Fet Buffer for amplifiers
source: http://cappels.org/dproj/edfet/edfet.html
The EDFET drives like a FET, but with the bias stability of bipolar. Amps of output current can be controlled by milliamps of input current. The current gain is a design choice dictated by bandwidth. Two of things you have to consider when adding a power output stage to an op-amp circuit are the frequency response and the cross-over distortion in that stage.
This is especially true with wide band amplifiers, where the unity gain crossover needs to be at several hundred kilohertz. The stage is driven much the same as a complimentary pair output stage, but with the current gain that comes with using FETs., and with feedback within the output stage that that extends the buffer's bandwidth and regulates the quiescent current. More predictable operation allows the designer to design a circuit lower overall power dissipation and better closed loop stability.
The EDFET complimentary buffer is made up of a pair of unity gain buffers, one that drives in the positive direction and the other that drives in the negative direction. Pictured above is the positive driving half of the output stage.
Gain to make the output signal track the input signal comes from inverting transistor, Q1. The input signal is applied to the emitter of Q1 and the output of the amplifier is raised one diode drop to match the forward base-emitter drop of Q1, by diode connected transistor Q2. The buffer's offset is determined by the log of the magnitude of the mismatch in the emitter currents in Q1 and Q2, and it is directly proportional to the absolute temperature.
Since the saturation current usually isn't published for the transistors this expression is only usefully for appreciating the dependence of junction voltage on current and temperature. You can come up with your own value of I0 for a given transistor if you know all the other parameters and solve the above formula for I0. By the way, since, for most practical uses, you will be running at more than a thousand times the saturation current, the "+1" term can be dropped from practical calculations.
As an example, for the audio amplifier using a EDFET buffer shown in Figure 1. The following assumptions are applied: The maximum output voltage is 5 VDC with respect to ground, the power supply (VA) is 12 VDC, the maximum gate voltage is 8 VDC, the input capacitance, Ciss of the BUZ73 is 500 pf, and an...

Upgrading to BackTrack 5 R2
The long awaited release of the BackTrack 5 R2 kernel has arrived, and it’s now available in our repositories. With a spanking brand new 3.2.6 kernel, a huge array of new and updated tools and security fixes,
BT5 R2 will provide a more stable and complete penetration testing environment than ever before. We
will start a series of blog posts on how to upgrade, deal with VMWare, and even build your own updated BT5 R2 by yourself. For now though, here’s how to get the new kernel and all of the updated goodness:
1. Update and upgrade your BT5 (R1) installation:
apt-get update
apt-get dist-upgrade
apt-get install beef
reboot
Once that’s done, you should already have the new kernel installed as well as any last updates we have
for the official R2 release. You need to reboot to have the 3.2.6 kernel kick in.
2. OPTIONAL – Once rebooted, log back in, and get your pretty splash screen back.
fix-splash
reboot
On the next reboot, you should see the red console splash screen appear.
3. Verify that you are running a 3.2.6 kernel:
uname -a
You should see something like “Linux bt 3.2.6 …”
4. Feel free to install any or all of the new tools featured in BackTrack 5 R2:
apt-get install pipal findmyhash metasploit joomscan hashcat-gui golismero
easy-creds pyrit sqlsus vega libhijack tlssled hash-identifier wol-e dirb reaver
wce sslyze magictree nipper-ng rec-studio hotpatch xspy arduino rebind horst
watobo patator thc-ssl-dos redfang findmyhash killerbee goofile bt-audit bluelog
extundelete se-toolkit casefile sucrack dpscan dnschef
5. Add the new security updates repository to /etc/apt/sources.list, and run another upgrade.
echo "deb http://updates.repository.backtrack-linux.org revolution main microverse
non-free testing" >> /etc/apt/sources.list
apt-get update
apt-get dist-upgrade
During the last upgrade you’ll be asked about file revision updates. Make sure to always keep the
locally installed file. Feel free to press “Enter” and accept all the defaults.
6. Some of the newly installed services will be set to start on boot. We like disabling these as needed:
/etc/init.d/apache2 stop
/etc/init.d/cups stop
/etc/init.d/winbind stop
update-rc.d -f cups remove
update-rc.d -f apache2 remove
update-rc.d -f winbind remove
And…you’re done! Expect a more comprehensive introduction to BT5 R2, on the day of the Official
release – March 1st! The BackTrack 5 R2 ISOS will we available for download from site on March 1st
via Torrent only. HTTP links will be added a few days later.
