2. Power MOSFET - Wikipedia

   en.wikipedia.org/wiki/Power_MOSFET

   NXP 7030AL - N-channel TrenchMOS logic level FET IRF640 Power Mosfet die. The power MOSFET is the most widely used power semiconductor device in the world. [3] As of 2010, the power MOSFET accounts for 53% of the power transistor market, ahead of the insulated-gate bipolar transistor (27%), RF power amplifier (11%) and bipolar junction transistor (9%). [24]

3. RF power amplifier - Wikipedia

   en.wikipedia.org/wiki/RF_power_amplifier

   A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [1] Typically, RF power amplifiers are used in the final stage of a radio transmitter , their output driving the antenna .

4. Two-wire circuit - Wikipedia

   en.wikipedia.org/wiki/Two-wire_circuit

   Two-wire circuits in new installations are limited to intercom and military field telephone applications, though these too are being supplanted by modern digital communication modes. To communicate in both directions in the same wire pair, conversion between four-wire and two-wire was necessary, both at the telephone and at the central office .

5. Gate driver - Wikipedia

   en.wikipedia.org/wiki/Gate_driver

   A gate driver is a power amplifier that accepts a low-power input from a controller IC and produces a high-current drive input for the gate of a high-power transistor such as an IGBT or power MOSFET. Gate drivers can be provided either on-chip or as a discrete module. In essence, a gate driver consists of a level shifter in combination with an ...

6. TrueCrypt - Wikipedia

   en.wikipedia.org/wiki/TrueCrypt

   Months later on 7 June 2004, TrueCrypt 2.0 was released. [1] The new version contained a different digital signature from that of the original TrueCrypt Team, with the developers now being referred to as "the TrueCrypt Foundation." The software license was also changed to the open source GNU General Public License (GPL). However, given the wide ...

7. Push–pull output - Wikipedia

   en.wikipedia.org/wiki/Push–pull_output

   A push–pull amplifier draws little power with zero signal, compared to a class-A amplifier that draws constant power. Power dissipation in the output devices is roughly one-fifth of the output power rating of the amplifier. [7] A class-A amplifier, by contrast, must use a device capable of dissipating several times the output power.
