Analog VLSI Graphical Models

This project explores performing statistical signal processing with analog circuits. The first instantiation is a low-complexity circuit for phase acquisition and tracking of a pseudo-random sequence generated by an LFSR. Eventually we hope to scale the complexity of this kind of cicuitry to be able to perform any high-speed signal processing desired for a digital wireless front-end. In many application domains, this approach could be 10 to 100 times more efficient in terms of power consumption and square millimeters of silicon than the equivalent digital signal processor (DSP).
