【Abstract】 In this paper, a novel method are presented to realize narrow-band switched-capacitor filter using two-phase clock signal. The resulting filter is not only lowerly sensitive, ease and convenient to be implemental but also of useful integration and generality. As an example, a 6th order elliptlic narrow-band switched-capacitor filter is given. The experimental results are in good agreement with theory. The circuit has certain practical value.更多还原
