  • Abstract
    A discrete-time noise-shaping modulator is shown to encode the logarithm of its input without using logarithmic or exponential elements. Used as an A/D converter, the proposed modulator may replace a logarithmic amplifier followed by a uniform quantiser. Used as a D/A converter, it may replace a multibit piecewise logarithmic circuit with a single-bit circuit
