Basic Building Blocks
Publisher Summary
This chapter takes a look at the triode valve, how to choose operating conditions, and describes what effect these choices have on the AC performance of the stage. The analysis uses 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. The most common use of a valve is amplification. Therefore, one needs to know how to configure and bias the valve so that it can amplify in a linear manner and minimize distortion. The anode characteristics are the most useful set of curves for a valve, and the plot shows anode current Ia against anode voltage Va, for differing values of grid to cathode voltage. The ...
