hello everybody .... I'm a new member here ... I like ur website and i want to benefit from it

sorry if my language is not so good

my question is about analog multiplier ,

I want a circuit uses analog multiplier as essential element , please

 

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 :

or what you might use a multiplier for?

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:
