Summary:
This paper presents arithmetic and piecewise linear circuits operating directly on firstorder multi-level sigma-delta modulated signals. The circuits can operate slower than sigma-delta domain binary circuits and can be more compact than Nyquist rate multi-bit circuits to obtain the same precision of processing. Thus, the proposed circuit technique will provide well-balanced signal processing systems both in operation speed and in circuit scale.
