Yes, two or four diodes, a triangular voltage and a series resistor are all you need. The offset voltage to the diode networkJust connect the triangle waveform generator to the diodes (with the resistors) and increase the amplitude until it starts to round off.

Thanks for the page.. This one looks so complicated though! Hey if possible can you answer the above post having a few questions..
Assuming an ideal diode characteristic (almost realistic in this case), you'll get an optimal triangular input voltage. For single 1N4148The circuits rely on the soft 'knee' in the voltage-current curve of the diode. You cannot change where that happens so yes, it has to work at a particular voltage. You can alter the 'softness' a little by changing the series resistor.

Ok so I was working on generation of sine waves from triangular wave. One circuit I able to successfully test on pspice using differential pair and op-amp. thanks to FvM and other seniors for the help!
