Titel
Wave-SC-filters with reference filters using lattice structures
Abstract
The design and realization of symmetrical wave-SC-filters with reference using lattice structures will be demonstrated. As in the case of wave digital filters these filters can be realized with a minimum amount of hardware. For a n-th order filter only n+1 operational amplifiers are required. The resulting circuits operate with a nonoverlapping two-phase clock and are fully stray-insensitive. As a design example a 5th order PCM-lowpass will be numerically and experimentally analysed. (IMS)
