    There are many ways to do this:

    1. FET
    2. transconductance amplifier
    3. variable gain amplifier
    4. analog multiplier chip

    Are you asking how to make a multiplier, or what you might use a multiplier for?

    • Like an analogue circuit to calculate the RMS value of a waveform?
    • Something to calculate the power in a circuit by multiplying the current by the voltage?
    • An amplitude modulator? A frequency converter for a (superheterodyne) radio receiver?

    I have a homework to search on the internet about circuit uses analog multiplier (like Gilbert multiplier cell)
    so i want a drawing for this circuit .

    Mr Adjuster :
    exactly but i want a Scheme drawing for any of the circuit you mentioned

    The datasheet of a balanced analog multiplier IC has many circuit examples.
    Here is the datasheet for the MC1496:
