Abstract :
A method for synthesising a parasitic-compensated switched-capacitor (SC) ladder filter with the property that the worst-case sensitivity of its amplitude response is zero at every reflection zero is presented. The stopband sensitivity of this SC filter is low as well as its passband sensitivity.
