This paper presents a speculative Byzantine algorithm base on Zyzzyva which has high performance for applying to peer to peer (P2P). We adopt a hybrid P2P system with monitor node to improve the performance of pure P2P system.
This paper describes techniques for creating a low-power SAR ADC with an error-correcting non-binary successive approximation algorithm; it is suitable for low power applications, performs digital error correction, and does not require analog calibration. Two techniques have been proposed for implementing low-power SAR ADCs: use of two comparators, and a charge-sharing architecture. However these...
This paper describes a redundant algorithm for a highly reliable Successive Approximation Register (SAR) ADC where mistakes of comparator decision can be digitally-corrected. We generalize a conventional non-binary search algorithm which requires more conversion steps in the SAR ADC than the binary search algorithm, and clarify which decision errors can be digitally-corrected with the derived redundant...
This paper describes a new architecture for high-resolution digital PWM (DPWM) generator used in digitally-controlled DC-DC converters, PWM time resolution is determined by the difference between two (or more) gate delays, while that of conventional DPWM circuits is determined by gate delay itself. The proposed DPWM circuit can achieve fine time resolution with small circuits, and has low power consumption...
