Low-Sensitivity Active-RC Allpole Filters Using Optimized Biquads
In this paper we present an optimal design procedure for secondand third-order active resistance-capacitance (RC) single-amplifier building blocks that are used to build a high-order tolerance-insensitive allpole filter. The design procedure of low-sensitivity, low-pass secondand third-order active-RC allpole filters, with positive feedback, has already been published. The design was extended t...
متن کاملLow-Noise Active-RC Allpole Filters Using Optimized Biquads
In this paper it is shown that active-RC filters can be designed to have low-sensitivity to passive components and at the same time possess low output thermal noise. The design procedure of low-noise and low-sensitivity, positive-feedback, secondand third-order low-pass allpole filters, using impedance tapering, has already been published. The noise analysis in this paper was extended to the hi...
متن کاملLow-Sensitivity, Low-Power Active-RC Allpole Filters Using Impedance Tapering
A procedure for the design of allpole filters with low sensitivity to component tolerance is presented. The filters are based on resistance–capacitance (RC) ladder structures combined with single operational amplifiers. It is shown that by the use of impedance tapering, in which L-sections of the RC ladder are successively impedance-scaled upwards, from the driving source to the amplifier input...
متن کاملLow-Noise, Low-Sensitivity Active-RC Allpole Filters Using MATLAB Optimization
The application of Matlab, combining its symbolic and numeric calculation capabilities, to calculate noise and sensitivity properties of allpole active-RC filters is shown. Transfer function coefficients calculations, as well as plotting of amplitude-frequency and phasefrequency characteristics (Bode plots) have been performed using Matlab. Thus, using Matlab a comparison of different design st...
متن کاملLow-sensitivity active-RC high- and band-pass second-order Sallen & Key allpole filters
The design procedure of low-sensitivity, low-pass (LP) 2-and 3-order class-4 Sallen and Key active resistance-capacitance (RC) allpole filters, using impedance tapering, has already been published [1]. In this paper desensitization using impedance tapering is applied to HP and BP 2-order filters. It is shown that HP filters have dual properties to LP filters in the sense of sensitivity. Among v...
