專利摘要 |
The present invention discloses a sigma-delta modulator architecture capable of automatically improving dynamic range and a method for the same. Based on the concept that different dynamic ranges of a sigma-delta modulator can be obtained via adjusting the signal power gain thereof, the present invention provides a novel algorithm to implement an automation program. The present invention finds out several sets of dynamic-range curves to improve the overall dynamic range. Via a high-level sigma-delta modulator architecture, the present invention can calculate the required feedforward coefficients. Furrther, the present invention install in the sigma-delta modulator architecture with four additional components, including a peak detection unit, a comparator unit, a digital coefficient control unit and a switch unit, to dynamically detect the output of the modulator and dynamically modify the feedforward coefficient of the sigma-delta modulator. Thus is extended the dynamic range of the sigma-delta modulator. |
