An integrated circuit implementation of a PSK backscatter modulator for passive radio frequency identification (RFID) transponders is proposed. Such modulator offers a significant reduction of the power consumption with respect to other schemes already presented in the literature. Furthermore, the topology of the proposed modulator allows us to control its output resistance so that only a negli...

We present a dual traveling-wave electrode InP-based Mach-Zehnder (MZ) modulator with an n-i-n waveguide structure. An electrical input/output interface placed on one side of the chip helps us to drive the modulator in a push-pull configuration. This configuration provides the modulator with great advantages such as reduced driving voltage amplitude, chirp-free operation, and the ability to sup...

A scheme to achieve a wideband linearized silicon Mach-Zehnder (MZ) modulator is proposed. The modulator consists of a single MZ interferometer with identical reverse-biased silicon diode phase shifters in both arms, driven in a push-pull configuration. It is shown that the 3rd order nonlinearity of the modulator can be eliminated by canceling the nonlinearities from the silicon phase shifters ...

Modulator is an endogenous low-molecular-weight regulator of both glucocorticoid and mineralocorticoid receptors as well as protein kinase C. Structural analysis of modulator purified to apparent homogeneity suggests that it is a novel ether aminophosphoglyceride. In this report, we show that modulator inhibits cytosolic human glucocorticoid receptor (GR) complex activation as measured by DNA-c...

Ion energy distributions (IEDs) play an important role in material processes and thin film deposition. We developed a newly designed multistep pulsed power supply (modulator) for the asymmetric bipolar sputtering (ABPPS) technology studied effect of reverse bias voltage improving properties films through Ti Using ion analyzer, we confirmed IEDs relative intensity under modulator at substrate po...

A novel radio frequency (RF) phase measurement method that uses optical modulation was proposed. The mathematical model of Mach–Zehnder modulator (MZM) characterization reviewed. By measuring the output sideband power modulator, difference electric signals fed to experimentally measured, and picosecond-level accuracies were achieved. This technique is expected be useful for radio-over-fiber-bas...

This paper proposes a new architecture of the feedforward multibit ΔΣAD modulator for low power application. The SQNDR (Signal to Quantization Noise and Distortion Ratio) of ΔΣAD modulator is limited by the dynamic range of the input signal and non-idealities of circuit building blocks, particularly by the harmonic distortion in amplifier circuits. In a full feedforward ΔΣAD modulator structure...
