| Abstract(in English) | Recently, a golden-ratio-encoder (GRE) was proposed for A/D conversion based on the β-encoder with a radix equal to the golden ratio, φ. GRE is an A/D converter with an exponential bit-rate accuracy with respect to the bit length L, and robustness for circuit parameter deviations. These features are useful for integrated circuit implementations with nanometer semiconductor processes, in which the characteristics of the circuit elements are degraded. We have shown a switched-capacitor circuit implementation of GRE. Moreover, we have evaluated the effects of offset voltage and finite gain of the op-amp, and the effects of offset voltage and output voltage of a comparator. In this paper, we propose a fully-differential circuit implementation of switched-capacitor GRE circuit. Then, we confirm the basic characteristics of the proposed circuit through SPICE simulations with ideal circuit components. |
