    In class we made a F/V converter using an LM331 chip. Now, using the LM331's block diagram, we're supposed to make an equivalent circuit.
    I don't even know where to start. We can use any combination of op-amps, transistors, etc.
    Can someone point me in the right direction?
    Thanks for your time.

    Treat the 331 block diagram as electronic building blocks. Find components that will perform the equivalent function for each block.
