A new scheme of a complex section with the use of inverting integrators implemented on two operational amplifiers, capacitors and switches is described. A procedure for calculating complex band-pass filters based on complex sections implemented using switched capacitors is considered. As an example, two basic schemes of a complex band-pass filter with a low-frequency Butterworth prototype of the 3rd order are developed. The first scheme is implemented on the basis of operational amplifiers and RC elements, and the second scheme contains operational amplifiers, capacitors and switches. The circuit solutions of the complex filters were simulated in the Micro- Cap software environment. Amplitude-frequency responses (AFRs) of complex filter were calculated for both the first and the second schemes. The frequency responses of both filters were found to be almost identical with each other. Conversion of an impulse signal was simulated in the time domain. Both filters produced the same output signals. The simulation results have confirmed the efficiency of the proposed method for calculating complex filters on switched capacitors.
