J energies with a repetition rate from 50 to 250 khz. Whenever we applied a positive half cycle at the input of the primary transistor q1. As no coupling devices are used, the coupling of the amplifier stages is done directly and hence called as direct coupled amplifier. No dc current flows through the load or through the signal source. Dc directcoupled amplifiers uac coupled small signal amplifiers advantages. The electronic circuit analysis notes pdf eca notes pdf book starts with the topics covering classification of amplifiers, analysis of cascaded rc coupled bjt amplifiers cascode amplifier, general frequency considerations, mos small signal model, classification of feedback on amplifier characteristics, classification of oscillators, class a.
