A new electronically controllable sinusoidal oscillator employing two voltage differencing-differential input buffered amplifiers (VD-DIBAs), two grounded capacitors, and one grounded resistor is presented. The proposed configuration offers (i) independent control of condition of oscillation (CO) and frequency of oscillation (FO) formerly by resistance and later through transconductance, (ii) low active and passive sensitivities, and (iii) a good frequency stability. The workability of the proposed configuration has been demonstrated by SPICE simulation.
