Weighted summation (W-SUM) operation of multi-input signals plays an important role in signal processing, image compression and communication systems. Conventional digital LSI implementation for the massive high-speed W-SUM operations usually consumes a lot of power, and the power dissipation linearly increases with the operational frequencies. Analog or digital-analog mixed technology may provide a solution to this problem, but the large scale integration for analog circuits especially for digital-analog mixed circuits faces some difficulties in terms of circuit design, mixed-simulation, physical layout and anti-noises. To practically integrate large scale analog or digital-analog mixed circuits, the simplicity of the analog circuits are usually required. In this paper, we present a solution to realize the parallel W-SUM operations of multi-input analog signals based on our developed digital-controlled analog operational circuits. The major features of the proposed circuits include the simplicity in the circuitry architecture and the advantage in the dissipation power, which make it easy to be designed and to be integrated in large scale. To improve the design efficiency, a Top-Down design approach for mixed LSI implementation is proposed. The proposed W-SUM circuits and the Top-Down design approach have been practically used in the LSI implementation for a series of programmable finite impulse response (FIR) filters and matched filters applied in adaptive signal processing and the mobile communication systems based on the wideband code division multiple access (W-CDMA) technology.
