Sažetak
The design procedure of 2nd- and 3rd-order low-sensitivity low-power allpole active resistance-capacitance (RC) filters, using the impedance tapering design method has already been published. Beside sensitivity minimization the impedance tapering was used for output noise minimization and output dynamic range maximization. In this paper it is shown that active resistance-capacitance (RC) filters can also be designed for low input thermal noise. The design procedure of filters with minimum input noise is very similar to the design of minimum sensitivity filters in its most important steps. Thus, the judicious selection of component values account for the considerable decrease in sensitivity and in input thermal noise. The minimum noise at the filters input is obtained by minimizing the total resistance of the filter circuit. The noise analysis was performed on the 2nd- and 3rd-order (class 4) Sallen and Key low-pass filter sections using MATLAB.
