| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently, a golden-ratio-encoder (GRE) was proposed for A/D conversion based on the $\beta$-encoder with a radix equal to the golden ratio, $\phi$. 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. |
