Claim Text:
1. A feed forward sigma-delta analog to digital conversion modulator, comprising: an input end capacitor switching circuit, for receiving an input timing control signal, an input voltage and a capacitor switching signal, and generating an integration input signal; a feed forward integrator, for receiving the integration input signal, a continuously progressive control signal and an input timing control signal, and generating an integration output signal; a multi-bit quantizer, for receiving an integration output signal and a quantization reference control signal, and generating a modulation output signal; a continuously progressive control circuit, for receiving the modulation output signal, and generating the quantization reference control signal, the continuously progressive control signal and a weighted average data signal; and a weighted average data circuit, for receiving the weighted average data signal, and generating the capacitor switching signal.
