In the presented paper, a sensorless driver circuit is designed, constructed and tested to control two types of three-phase Switched Reluctance Motor (SRM). The presented control algorithm has three steps. In the first step, the SRM is controlled by an open-loop method. In the second step, mathematical model of the SRM phase, motor parameters and flux-current-rotor position relation are used in...

In this paper, an energy efficient design of asymmetric high performance low swing CMOS driver receiver pair for driving global on-chip interconnects is proposed. The design is implemented on 90nm CMOS technology using HSPICE. The proposed CMOS driver receiver pair reduces the power by 35.45% as compared to the static driver with conventional level converter (CLC). The design is also compared w...

We designed an emission control driver using P-type TFTs to adjust the light emission period of an active matrix organic light emitting diode (AMOLED) displays. The P-TFT emission control driver has achieved rail-to-rail driving and low power consumption. Using this circuit, we can control peak brightness dynamically to reduce panel power consumption and motion blur. We developed 4.3 inch WQVGA...

The paper proposes a novel self-reference voltage pre-regulator for LED driver chip. The system modeling of the self-reference voltage pre-regulator is established, which is composed of pre-regulator circuit and reference voltage generating circuit. The reference voltage generating circuit generates a reference voltage, in which the circuit returns the reference voltage as the reference voltage...

Abstract As the switching speeds and densities of Digital CMOS integrated circuits continue to increase, output switching noise becomes more of a problem. This paper reports a novel design technique which aids in the reduction of switching noise. The output driver stage is analyzed through the use of an equivalent RLC circuit. The results of the analysis are used in the design of an output driv...

This paper presents and implements a single-stage high-power-factor light-emitting diode (LED) driver with coupled inductors, suitable for streetlight applications. The presented LED driver integrates an interleaved buck-boost power factor correction (PFC) converter with coupled inductors and a half-bridge-type series-resonant converter cascaded with a full-bridge rectifier into a single-stage ...

High power Light Emitting Diodes (HPLEDS) are adopted for lighting purpose, making them the fastest growing light source worldwide. This paper discusses HPLED lamp of various shapes with different lux levels and different heat sink requirements when used for indoor lighting. To provide constant current to LED, a driver circuit is designed using a dc to dc converter and a microcontroller. The in...

The paper presents a new quasi adiabatic logic family that uses two complementary split-level sinusoidal power supply clock for digital low power applications such as sensors. The proposed two-phase adiabatic static CMOS logic circuit (2PASCL) is using the principle of energy recovery and adiabatic switching. It has switching activity that is lower than dynamic logic and can be directly derived...
