TRANSCONDUCTANCE [10 records]

Record 1 2012-02-16

English

Subject field(s)
  • Electric Currents
  • Vacuum Tubes (Electronics)
CONT

For example, a bias voltage is applied to a transistor in an electronic amplifier to allow the transistor to operate in a particular region of its transconductance curve. For vacuum tubes, a(much higher) grid bias voltage is also often applied to the grid electrodes for precisely the same reason.

OBS

grid bias voltage: term officially approved by the Electronics and Telecommunications Terminology Committee.

CONT

La tension de polarisation de grille est telle [qu'un] tube sera conducteur avec une tension d'écran.

OBS

tension de polarisation de grille : terme uniformisé par le Comité d’uniformisation des termes de l’électronique et des télécommunications (CUTEL).

Record 2 2012-02-16

English

Subject field(s)
  • Vacuum Tubes (Electronics)
CONT

Although [a] single-balanced mixer consumes less power, it provides less conversion transconductance, lower linearity and higher noise figure. [A] local oscillator signal is not suppressed properly by the mixer, so that it feeds through to the output.

OBS

conversion transconductance : term officially approved by the Electronics and Telecommunications Terminology Committee.

Record 8 2002-11-13

English

Subject field(s)
  • Amplifiers (Electronics)
CONT

We have to consider what type of gain device is suitable for this application. Actually the choice is simple : Bipolar devices have too low an input impedance to be useable, and tubes have too little gain to be used in a single stage power amplifier. The only usable device is the power Mosfet, which is a transconductance device like the tube, and has a high input impedance, but operates with enough gain at high enough currents to be driven directly by line-level signal.
