Research output: Patent


A low power sigma-delta modulator architecture capable of dynamic detection of output signal strength to change dynamic range, method for implementing low power circuit thereof, and method for correcting and extending dynamic range of the sigma-delta modulator automatically utilize an automatic correction unit to detect output signal strength of the sigma-delta modulator system, compare system input signal specifications and come out multiple sets of dynamic range curves, and thereby extract an appropriate combination of system order and feed-forward coefficients to extend the system dynamic range. The circuit architecture of the automatic correction unit is in a digital circuit form, including a digital signal processor, a counter and register array.
