Abstract

This paper proposes and simulates a fourth order single-loop modulator with feed forward structure which covers the ADSL-standard bandwidth. Design of this modulator employs a low distortion structure suitable to target bandwidth to achieve its objectives. To achieve the required specifications of target standard, a fourth order modulator with oversampling rate of 14, bandwidth of 1.2 KHZ, SNR of 87 dB, and accuracy of 14.2 bits is designed and simulated. Block diagram of the proposed structure is also presented
