The first transistor-based impedance matching circuit for radio-frequency (RF) applications is introduced in this paper. It adapts arbitrary output impedances of RF blocks to desired values between 50 and 250 , from 0 to 5GHz, while occupying only 0.005mm2 of circuit area in a 0.35μm SiGe BiCMOS process. Its superiority over traditional passive-element networks can be resumed by the following f...

There has been a significant volume of recent work on FPGA designs for pattern matching. Although various pattern-matching architectures have been presented, attempts to compare different designs have been inconclusive, or even misleading, due to the lack of a common evaluation framework. In this paper, we present an analytical model of FPGA pattern-matching architectures that quantitatively ex...

Power optimization can reduce heat dissipation costs and has become an important step of circuit logic synthesis. Because the power for mixed polarity Reed–Muller (MPRM) circuits is a combinatorial problem, in this paper, we first propose multilevel adaptive memetic algorithm (MAMA), which includes global exploration optimizer, local heuristic initial population optimizer. We use proposed diffe...

Time-stepping finite element method (FEM) has become a powerful tool in solving transient electromagnetic fields. The formulation can include complex issues such as time harmonics and space harmonics, nonlinear magnetic property of iron materials, external circuit and mechanical motion in the system equations. However, as the derivatives of physical quantities are usually unknown at the initial...

The execution of quantum algorithms requires two key considerations. On the one hand, it should meet connectivity constraint requirements circuit mapping for architectures, and on other needs to consider reducing probability errors in circuits as much possible. This paper proposes a novel optimization technique based template matching that satisfy both requirements. method can significantly red...
