Some lithium oxyhalides have been proposed as low-cost solid electrolytes for having room-temperature Li+ conductivity close to commercial liquid electrolytes, but with the advantages of enabling higher energy densities through...

A novel approach for designing infinite impulse response (IIR) switched-capacitor filters, based on the optimum allocation of poles and zeros of a transfer function, implemented by a direct-form topology using finite-impulse response (FIR) cells as basic building blocks is presented. As a consequence, low sensitivity with respect to capacitance ratio errors in both passband and stopband frequencies, low power consumption, and improved group delay response are achieved. Comparisons with classical IIR and linear-phase FIR filter designs are made. An illustrative design example including simulation and experimental results obtained with a prototype filter are provided.Index Terms-Delay equalizers, direct form, pole and zero assignments, sensitivity, switched-capacitor filters.
