Abstract
A new variable frequency sinusoidal oscillator configuration is proposed. Only two current feedback operational amplifiers (CFOAs), two grounded capacitors and three resistors are used. The frequency and condition of oscillation can be independently adjusted by means of single grounded resistors. Also, very high frequency operation is demonstrated and an example application of an oscillator which does not require an external capacitor presented
