摘要：An analog front end circuit is provided, which comprises at least one convertingcircuit. Each converting circuit further comprises a clamper, a low-pass filter, an inputbuffer and a sigma-delta analog-to-digital converter. By using the sigma-delta analog to

digital converter, the invention not only increases the resolution, but reduces the orderof an anti-aliasing filter, therefore reducing the size and the power consumption of theanalog circuit.
