Hi! I need a simple schematic diagram of an oscillator circuit that would produce a sine wave and varying frequency. And its bandwith should not be less than 100 kHz. Thanks!!!

Been there, done that: Boing, boing, bounce, bounce.
The 10Hz settling time was nearly forever. I ended-up using back-to-back LEDs as a peak limiter of the bouncing to speed-up the settling.
I made this circuit, using MC33077 high-speed opamps, a dual supply and LEDs. I swapped the R's and C's for lower distortion. It reached past 100kHz: **broken link removed**

It's the price you pay for low distortion, if low distortion isn't an issue you can use diode clamps (as in your circuit) - but distortion will be many times higher.
Well he Didn't say he needed Low distortion, but the XR2206 is capable of down to 0.5% Thats not too bad. And it Definately covers the Frequency range, plus the bonus of other waveforms.
You could try a common emmitter phase shift oscillator, 100kHz is just about high enough of an LC oscillator, a hartley or colpitts should be also easilly doable.
