Predistorted RC Active Filters with Low Pole Sensitivity to Finite GB of Single Pole Operational Amplifier
Summary :
A synthesis of high frequency active RC filters using an operational amplifier with single pole characteristics is presented. As a measure of the quality of filters, the pole sensitivity with respect to the gain bandwidth product GB of the amplifier is used and it is shown that the absolute value of the pole sensitivity has a minimum limit. The synthesis is based on the predistortions of Q and center frequency errors caused by the finite GB of the amplifier. The proposed circuit has quite stable temperature characteristics and examples show illustrative differences of the temperature responses between the proposed circuit and conventional ones.
