Chapter 2. Basic Building Blocks
In this chapter, we will look mainly at the triode valve, how to choose operating conditions and what effect these choices have on the AC performance of the stage. The analysis will use a combination of graphical and algebraic techniques, which has the advantage of being quick to use, and the results of the theory agree well with practice. This last point might seem to be an obvious requirement, but it is one that is sometimes overlooked.
The Common Cathode Triode Amplifier
The most common use of a valve is amplification. Therefore, we need to know how to configure and bias the valve so that it can amplify in a linear manner and minimise distortion. We will begin by investigating the
anode characteristics of an ECC83/12AX7 ...
