[ Ask ] sine wave oscillator produce 5 volt pp , 40khz

Hello,
I am Ibnu , this is my first post . I am very happy join . I got difficult to make ocillator circuit to produce 40 khz . The output is 5 volt peak to peak . I got this homework yesterday and i am not yet get this lesson totally . I searched in google but i can`t get solving . I have to finish tomorrow , Can anyone help me?
Thanks

What means: "input is 5 volt peak-to-peak" ?
An oscillator has no input (except dc supply).
 


I posted a link to another thread on this forum, in which some sugestions were provide.

However, you can try with that circuit :

Ibnu10, I am sure that many forum members are willing and able to help you.
But at first - you should give us some more information about your task.
For example - what is the required waveform? Squarewave or sinusoidal or something else?
Are you allowed to use opamps? Or only transistors?
Which power supply is available?
Any accuracy requirements ?
 


thanks for your answer . Okay , the detail is?
Output : sine wave , 5 volt pp , freq 40 khz .
Circuit use ic 555 . No any parameters . I want simplest way to made it

A 555 will produce a rectangular output, and with a little modification, it will produce a 50% duty-cycle square wave, but it will not produce a sine wave. You will need additional circuitry. If you look at the data sheet (or google) you'll find 50% duty-cycle circuit described.
