다국어 초록 (Multilingual Abstract)
Generally, the distortion of the negative feedback amplifier is reduced by a factor equal to the return difference (1 + β_1A_1), but the proposed feedforward amplifier is reduced by a factor equal to square of the return difference (1 + β_1A_1). In this paper, a feedforward amplifier with error correction is designed and implemented. So as to evaluate the characteristics of the harmonic distortion that the inverting feedforward amplifier is compared with that of the reference amplifier without feedforward error correction. It is confirmed that the proposed method should be able to improve much greater than compared with a conventional negative feedback amplifier. Therefore it should be noted that the proposed feedforward amplifier network is also acceptable for wide-band amplifiers and all of the network for the needless of harmonic distortion.
