—This paper presents a solid foundation for implementing analog vector-matrix multipliers (VMMs) in field-pro-grammable analog arrays (FPAAs). Custom analog VMMs have been demonstrated to be 1000 times more power efficient than commercial digital implementations. However, no previous analog VMM discussion has carefully provided all of the implementation and(More)
—The modulation and demodulation blocks in an orthogonal frequency-division multiplexing (OFDM) system are typically implemented digitally using a fast Fourier transform circuit. We propose an analog implementation of an OFDM demodulator as a means for reducing power consumption. The proposed receiver implements the discrete Fourier transform (DFT) as a(More)
—This paper presents a vector-matrix multiplier (VMM), which can be easily implemented on a field pro-grammable analog array (FPAA). This VMM can be synthesized directly into the switch-fabric of the FPAA, allowing for incredibly dense matrix operations. As an important aspect of this system, we utilize a complete chain of tools that compile the VMM design(More)
