Abstract

Time-Mode Signal Processing (TMSP) techniques are attempting to develop analog signal processing algorithms using primitive digital building blocks such as inverters and NAND/NOR gates. By doing so, the design of such analog circuits can be captured and automated by standard digital design tools and methodologies. In this paper, a method is proposed for designing high-order elliptic filters based on the operational simulation of LC ladder networks using a set of all-digital timemode building blocks (some new, some known). The design of a fifth-order elliptic filter having 1 dB passband ripple and 60 dB of stopband attenuation will be used to demonstrate the feasibility of the proposed design method.
