Active-R sinusoidal oscillators using the CFA pole

Three new sinusoidal oscillators using ihe curreni feedback amplifier (CFA) pole are presented. Two of the proposed sinusoidal oscillators consist of CFAs and resistors without external capacitances. Their oscillation condition and frequency can be independently controlled by two resistors. Experime...

Description
Summary:Three new sinusoidal oscillators using ihe curreni feedback amplifier (CFA) pole are presented. Two of the proposed sinusoidal oscillators consist of CFAs and resistors without external capacitances. Their oscillation condition and frequency can be independently controlled by two resistors. Experimental results were given lo demonstrate the feasibility of the proposed circuits. The proposed circuits will be suitable for high-frequency applications and integration in bipolar monolithic lechnology.
