Large-Flip Importance Sampling
نویسندگان
چکیده
We propose a new Monte Carlo algorithm for complex discrete distributions. The algorithm is motivated by the N-Fold Way, which is an ingenious event-driven MCMC sampler that avoids rejection moves at any specific state. The N-Fold Way can however get “trapped” in cycles. We surmount this problem by modifying the sampling process. This correction does introduce bias, but the bias is subsequently corrected with a carefully engineered importance sampler.

Design of Advanced Multiple-Valued D-FF Using Neuron-MOS
The proposed two types of multi-valued D flip-flops are NMAX-TG D flip-flop and NMIN-TG D flip-flop A NMAX-TG D flip-flop and a NMIN D flip-flop are composed of the components such as NMAX D flip-flops, NMIN D flip-flops and T-gate circuits. In the simulations, sampling frequencies of NMAX-TG D flip-flop and NMIN-TG D flip-flop are measured around 500 kHz and 1 MHz, respectively. The PDP parame...
متن کاملA Narrow-Band Delta-Sigma Frequency-to-Digital Converter
This paper describes a novel frequency-to-digital conversion technique based on the D flip-flop frequency deltasigma concept. It is shown that given some frequency constraints, there is no need for using a sampling frequency twice the maximum FM frequency. For narrow-band FM demodulation, it is further shown that by sampling the clock signal width the FM signal, the digital resolution is more e...

متن کاملDesign of Optimized Quantum-dot Cellular Automata RS Flip Flops
Complementary metal-oxide semiconductor (CMOS) technology has been the industry standard to implement Very Large Scale Integrated (VLSI) devices for the last two decades. Due to the consequences of miniaturization of such devices (i.e. increasing switching speeds, increasing complexity and decreasing power consumption), it is essential to replace them with a new technology. Quantum-dot c...
