Anotace: Two new electronically controllable sinusoidal oscillators each employing two Voltage Differencing Inverting Buffered Amplifiers (VDIBAs), two capacitors, and a single resistor have been proposed. The presented oscillators offer independent electronic control of Condition of Oscillation (CO) and Frequency of Oscillation (FO), and low active and passive sensitivities. The effect of non-idealities of the VDIBAs on the proposed oscillators is also investigated. The validity of the proposed structures has been confirmed by SPICE simulation with TSMC 0.18 µm process parameters.
