Systematic realization of low‐frequency third‐order sinusoidal oscillators

Summary In this paper, a systematic realization technique for low‐frequency third‐order sinusoidal oscillators (TOSOs) with independent control of condition of oscillation (CO) and frequency of oscillation (FO), employing minimum number of resistors and grounded capacitors, has been presented. Twelve new matrices have been systematically derived. These 12 matrices lead to four distinct low‐frequency sinusoidal oscillators with independent control of CO and FO. Workability of these proposed oscillators has been validated through experimental results of low‐frequency oscillations operating at 3.03 Hz, realized with off‐the‐shelf available IC AD844 type CFOAs. The total harmonic distortion of the presented oscillators is below 0.74%, and the frequency deviations are less than 1.06%.
