Abstract :
This paper presents the design of a current-feedback operational amplifier (CFOA) which is suitable for implementation with standard CMOS integrated-circuit technology of 0.35 mum. The characteristics of the CFOA are derived by using biases of plusmn2.5 V and Ibias=20 muA. The usefulness of the CFOA is demonstrated by designing mixed-mode biquads which realize the low-pass, high-pass, band-pass, notch and all-pass filter functions. As a result, it is highlighted that the SPICE simulations of the biquad working in voltage-mode are in good agreement with the biquad working in current-mode
