This paper introduce a new current mode Schmitt trigger circuit using a single Current Controlled Differential Difference Current Conveyor Transconductance Amplifier (CCDDCCTA). The circuit is designed using a single CCDDCCTA without any passive component. The proposed Schmitt trigger circuit is designed at a supply voltage of ±1.25V, bias voltage of -0.8V using PSPICE and the model parameter o...

In this paper we ultra low-voltage and high speed CMOS domino logic. For supply voltages below 500mV the delay for a ultra low-voltage NAND2 gate is aproximately 10% of a complementary CMOS inverter. Furthermore, the delay variations due to mismatch is much less than for conventional CMOS. Differential domino gates for AND/NAND and OR/NOR operation are presented. Keywords—Low-Voltage, High-Spee...

In this paper, inference model is proposed so as to analyze nonlinearly loaded dipole antenna. In modeling process, linear and nonlinear behavior of the problem is saved as simple and unchanged membership functions and the effect of incident wave on the induced voltage at different harmonies are then extracted easily. Consequently the model achieved is more efficient than previous studies using...

A fully differential opamp suitable for very-low voltage switched-capacitor circuits in standard CMOS technologies is introduced. The proposed two stage opamp needs a simple low voltage CMFB switched-capacitor circuit only for the second stage. Due to the reduced supply voltage, the CMFB circuit is implemented using bootstrapped switches. Minor modifications allow to use chopper stabilization f...

Operational Transconductance Amplifier (OTA) is one of the most significant building-blocks in integrated continuous-time filters. Here we design Low Power Low Voltage Bulk Driven OTA with a new concept of high-linearity OTA with controllable Transconductance is proposed. The OTA is simulated in a standard TSMC 0.18 mm CMOS process with a 0.6 V supply voltage. 1. INTRODUCTON Low-voltage (LV) an...

In this study, the negative differential resistance (NDR) phenomenon in two-terminal devices composed of pyrogallol-formaldehyde/ZrO2 composite materials is investigated. It demonstrated that NDR caused by electrothermal effects, which can be observed through dependence on both voltage and temperature. Additionally, it showed peak current peak/valley voltages effectively modulated using electri...

The security implications of on-chip voltage regulation on the effectiveness of various voltage/frequency scaling-based countermeasures such as random dynamic voltage and frequency scaling (RDVFS), random dynamic voltage scaling (RDVS), and aggressive voltage and frequency scaling (AVFS) are investigated. The side-channel leakage mechanisms of different on-chip voltage regulator topologies are ...

This paper studies satellite deorbit using electrodynamic tether (EDT) propulsion. Gaussian perturbation equations are used to model the orbital dynamics of EDT with environmental perturbations of electrodynamic force, aerodynamic drag and the effect of Earth’s oblateness. Differential equations for the induced voltage-current across EDT are derived and solved with boundary conditions determine...

A combination of cell culture and animal studies has recently shown that adhesion between neurexins and neuroligins played important roles in synapse initiation, maturation, and function. Binding of neurexin-1beta to neuroligin-1 triggers the postsynaptic clustering of the scaffold postsynaptic density protein 95, but the composition and timing of accumulation of glutamate receptors at those na...
