A 555 IC makes a simple square-wave oscillator.
A CD4047 IC makes an oscillator by adding one resistor and one capacitor.
A Cmos Schmitt-trigger logic inverter or gate makes a square-wave oscillator by adding one resistor and one capacitor.
Thanks for the help buddy, But i wanna make a Sine wave Oscillator. So can you tell me any easy way to design a Sine wave Oscillator? Throught which, i can convert any dc volt into A.c with frequency of my desire.
You'll possibly pay a lot of money to get an exemplar of obsolete ICL8038 (It's about 15$ at Ebay). Exar XR2206 is an
in-production function generator with sine output.
