• Cathode bias — In order for a vacuum tube (or valve) to operate in a fairly linear region of its characteristic curve, the grid element must be maintained at a bias voltage more negative than the cathode. This is called cathode bias.Early techniquesEarly… …   Wikipedia

• Cascode — The cascode is a two stage amplifier composed of a transconductance amplifier followed by a current buffer. Compared to a single amplifier stage, this combination may have one or more of the following advantages: higher input output isolation,… …   Wikipedia

• Ultra-Linear — is a term used to describe a type of electronic circuit that is used to couple a tetrode or pentode vacuum tube (also called electron valve ) to a load (e.g. to a loudspeaker).The circuit was developed by Alan Blumlein and patented in 1937 (… …   Wikipedia
