摘要：An example filter includes a differential amplifier and a resistor string coupledbetween output terminals of the differential amplifier. The resistor string may generate acommon mode sense voltage and an intermediate voltage at an intermediate node. A
feedback resistor is coupled between the intermediate node of the resistor string and aninput terminal of the differential amplifier, and a feedback capacitor is coupled between adifferential output terminal of the amplifier and the differential input terminal. Applyingfeedback in this manner may reduce area and power requirements of the filter to achieveselected frequency and gain performance.
