Abstract:
A delta-sigma modulator and a delta-sigma converter include an analog amplifying unit to amplify an analog signal and having at least a primary feedback coefficient, a quantizer to quantize an output signal of the analog amplifying unit, a DA converter to perform DA conversion on output of the quantizer and output a feedback signal, an adder-subtractor to input into the analog amplifying unit an analog signal obtained by subtracting the feedback signal from an analog signal input therein, a reset circuit to reset the analog amplifying unit at predetermined periods, and a control circuit to control the analog amplifying unit so that the analog amplifying unit operates as an integrator with the primary feedback coefficient of 1 until a predetermined period elapses after the reset circuit resets the analog amplifying unit and as an amplifier with the primary feedback coefficient of greater than one after the predetermined period has elapsed.

Claim (Index 12):
A delta-sigma modulator comprising:\n an analog amplifying unit to amplify an analog signal, the analog amplifying unit having at least a primary feedback coefficient; a quantizer to quantize an output signal of the analog amplifying unit; a DA converter to perform DA conversion on output of the quantizer and output a feedback signal to be fed back to the analog amplifying unit; an adder-subtractor to input into the analog amplifying unit an analog signal obtained by subtracting the feedback signal from an analog signal input therein; and a control circuit to control the analog amplifying unit so that the analog amplifying unit operates as an integrator with the primary feedback coefficient of 1 until a predetermined period of time elapses and as an amplifier with the primary feedback coefficient of greater than one after the predetermined period of time has elapsed.
