Abstract
A decimation filter includes a first circuit block for respectively delaying by one clock an input signal synchronized with a clock signal and for producing a plurality of delayed signals, adders for adding or merging by confluence buffers the delayed signals to obtain total signals and for feeding the total signals to one signal line, and a second circuit block for counting pulses of the total signals. The filter provides an analog-to-digital converter which processes signals at a high speed and which is resistive against overflow.
