摘要:... In this paper, a reasonable way of applying voltage is put forward by taking an electrostatic chuck in a real integrated circuit manufacturing process as a sample, applying voltage in the probe and the sample electrode, respectively, and comparing the measurement effect of the probe oscillation phase difference by amplitude modulation...

摘要:Abstract(#br)In this paper, the potential sensitivity in Kelvin probe force microscopy (KPFM) was investigated in frequency modulation (FM) and heterodyne amplitude modulation (AM) modes. We showed theoretically that the minimum detectable contact potential difference (CPD) in FM...

摘要:There has been much interest in the past two decades to produce experimental force profiles characteristic of the interaction between nanoscale objects or a nanoscale object and a plane. Arguably, the advent of the atomic force microscope AFM was instrumental in driving such...

摘要:Abstract(#br)We propose a novel differential amplitude pulse-position modulation (DAPPM) for indoor optical wireless communications. DAPPM yields advantages over PPM, DPPM, and DH-PIM ...

摘要:Abstract(#br)This paper presents an inductorless dual-output switched-capacitor DC–DC converter employing pseudo-three-phase swap-and-cross control (PTPSCC) and an amplitude modulation mechanism (AMM). The AMM circuit scales the amplitudes of the driving signals for the swi...

摘要:In this paper, we consider a free-space optical communication system using subcarrier intensity modulation (SIM) with general-order rectangular quadrature amplitude modulation (QAM) and operating over Gamma–Gamma turbulence channels subjected to pointing errors. We derive no...

摘要:... The source transmits its data adaptively using quadratic amplitude modulation. Two adaptive transmission schemes are proposed: the first scheme is named simple adaptive transmission scheme (SATS), and the second one is called high-performance spectral efficiency scheme (HPSES...

摘要:... In this paper, we propose a new Pulse Amplitude Modulation (PAM) method for the fine tuning of memristor conductance. The new PAM scheme is verified by the experimental measurement of real memristors, where the new PAM could reduce the pulse-to-pulse fluctuation in conductanc...

摘要:Abstract(#br)In this paper, we propose a precise and robust watermarking scheme based on the technique called amplitude modulation. A watermark is embedded in a color image by modifying the pixel values in the blue channel. At the receiver, the watermark bits are retrieved using ...
