Novel design procedure for class DE amplifier <Abstract> This paper presents a novel design procedure for class DE amplifier. And design curves of class DE amplifier with switch on resistance as functions of output Q, duty ratio, and load resistance are clarified. The feature of the proposed design procedure is that the waveform equations are never required. The design procedure requires only circuit equations and the design specifications. When circuit equations are derived, the other procedures for computations of design values are carried out with aid of computer. Therefore, it is possible to design class DE amplifier at any conditions, namely, at any output Q, any duty ratio, any switch on resistance and so on. By carrying out the circuit experiments, we denote that the experimental results agree with the calculation results quantitatively, and show the validity of the proposed design procedure. |
