  • Patent number: 8120518
    Abstract: A digital feedforward sigma-delta modulator in an analog-to-digital converter and its modulation method are disclosed. The modulator changes a feedforward path from an analog domain to a digital domain and processes it. The modulator integrates an analog input by using a plurality of integrators, weights them, quantizes them by using a plurality of quantizers in a digital domain to output digital signals, and then adds up the thusly outputted digital signals by using a digital adder. In case of a continuous time digital feedforward sigma-delta modulator (SDM), a digital signal outputted from the digital adder is weighted and then immediately inputted to the digital adder in the digital domain so as to be subtracted, allowing for digital feedforwarding. Because the feedforward signal is processed in the digital domain, the area occupied by an analog circuit and power consumption can be reduced.
