Circuit device for cancelling glitches in a switched capacitor low-pass filter and corresponding filter

摘要

The invention relates to a switched capacitor low-pass filter of a type which incorporates a plurality of integrator stages cascade connected together. The filter comprises at least one stage including the circuit device for cancelling out glitch pulses. This device is a deglitching circuit provided within the filter. Preferably, each stage in the filter is formed of a deglitching device which acts as a smoothing integrator. <IMAGE>
