    how to choose "PNP-NPN" mosfet transistors?

    yes, P-channel and N-channel mosfet transistor..i thought P-channel could be referred as PNP.. Thx, for the information.. Be the way, I also want to use them as a switch, but unfortunately i cound find ones that operates at 13.56 MHz and also @ 3 amp.. if u have a code for such transistors...

    which one to choose series LC or parallel LC resonant circuit?

    :confused: ..i found a book tells that parallel resonance is used for transmitter and receiver circuits. But no explanation about that.. anyone plz?

    which one to choose series LC or parallel LC resonant circuit?

    hello, My task is to transmit electricity via resonant inductive coupling using only one transmitter coil and one receiver coil.. I do not know which one is better to use for my transmitter circuit and receiver circuit, series LC or parallel LC as to make my coil resonate at specific...

    How to choose the right components for the following project?

    voltage divider rule, would it work here to reduce the input voltage? so you think BJT transistors are better to be used rather than Mosfet?

    How to choose the right components for the following project?

    i appreciate ur fast respond.. The transformer has a center tap secondary, so 12 V also could be used. But may i know why 24V is considered too high,plz? as far as i searched, epically at high frequencies push-pull mosfet is not recommended to work on its won, due to the undesired crossover...

    How to choose the right components for the following project?

    Hello, Im doing a resonant inductive coupling system as my project. A transformer used to step down the wall outlet (230V/50Hz) to 24V @ 3A, to be used as the input to a rectification circuit consisting of bridge rectifier and a filter cap. after that, there is a crystal oscillator circuit...
