ABSTRACT:
A multi-stage sigma-delta modulator including bit truncation between stages. The bit truncation reduces the number of bits that must be processed in subsequent stages and thus allows for faster response times. In some embodiments the gain of a feedback loop is selected to compensate for the bit truncation such that the sigma-delta modulator operates in a stable state.
