    [SOLVED] Stepping down sinusoidal voltage

    NO WE cannotttt!!! there are BJT's, FET's etc inside amplifiers and it can never work other way around , for eg how can u get output from the gate of any mosfet ???? you certainly can't . you need a voltage divider or use a transformer

    Negative Leakage Power for Antenna cell

    can you give some more details ? in what unit are you measuring power ? dBm ?

    doubt in clipping circuit

    bro you actually measured it across that source only, what you need to do is to place a resistor in series with that diode and then attach your probe parallel to that resistor .

    Error & Warning in Cadence

    Goto library manager-- edit---then you will see all the libraries there,you create a library by any name u desire and infront of that you'd hav to declare the path (that you will find in the properties of that lib file) ,just place your path and ur new library would be added :)

    electromagnetic energy to kinetic energy

    https://en.wikipedia.org/wiki/Kinetic_energy it explains what u need i suppose.

    Which RF IC to buy [Help]

    bro i'v been working on PA and it completely fulfills your specifications. it can go upto GHZ range and could esily have Pout of 30dBm (greater than what u want) easily, besides u can get a hand on different research papers also. my advice u shud go for PA. :)

    Layout of NMOS-transistors in series

    yes you can use deep nwell transistors, connect the 5th terminal to VDD that will reverse bias the junction and there would be no such leakage as well. :)

    electromagnetic energy to kinetic energy

    you forgot to mention what u need to find. please mention that and be specific :) if u need to find the velocity or other such parameter, the equation would be 0.5m(v^2)=QV here V=voltage Q is charge (i.e W=QV ,ke is replaced by workdone due to any electromangetic field) maybe this is what u need.

    Beginner Level CMOS circuit designing and parameter variation

    if u want to simulate just the circuit without changing the internal architecture you can easily use multisim,proteus, but if you need responses at very high frequencies or even changing the parameters is allowed in mentor graphics . thats available . :)

    [SOLVED] Solar power phone charger

    Re: Need help with solar powered mobile charger...please see!! due to the sameeeeeee reason,the current that sony Xperia needs isnt provided my the solar panel, but since ur new phone might have needed just the amount of current the solar panel produces dats y it works fine with it. if not...

    enable an lcd using a pic output

    from the Uc connect a 1k resistor with the base of any npn transistor (2222 will do),connect the collector with 7805's 5v i.e pin 3,and connect a 1k resistor with the emitter of 2222 and ground the other part,from the emitter u'l get the desired output i.e 5v provided that you have given the...
