Abstract
A very-low-sensitivity fully differential bandpass switched-capacitor filter (SCF) using the low-pass-to-high-pass transformation and the pseudo-two-path technique is proposed. Although this bandpass SCF is of the parasitics-compensated type, it has the useful property that the worst-case sensitivity becomes zero at every attenuation zero. The immunity to common-mode noise by virtue of the fully differential configuration is another advantage. A design example is presented and analyzed.<>
