A Low Cost Sensorless Control Drive Circuit for of Low Voltage Switched Reluctance Motor

Shaft position sensing is an essential part of switched reluctance (SR) motor drive In order to synchronize the pulses of phase current with the period of rising inductance of the proper motor phase. Direct sensors such as, Hall effect and optical encoder are commonly used in SR motors. The purpose of this paper is to present an indirect shaft positioning sensing known as "sensorless " control ...

LOW VOLTAGE PAs Techniques for Low Voltage Power Amplifier Matching

There is rapid expansion in the use of short range digital wireless systems [1], using the license-free allocations around 915 MHz in the USA and 869 MHz in Europe that permit up to 1 watt output power. These RF systems now use digital signal processing (DSP) for modulation and demodulation so to get better circuit packing density, and take advantage of finer IC process geometries that generall...

Hybrid Voltage Regulator for Low Voltage Applications

of the Thesis Fully Integrated Hybrid Voltage Regulator for Low Voltage Applications by Yongwan Park Master of Science in Electrical Engineering Stony Brook University 2016 A novel hybrid regulator topology is proposed to alleviate the weaknesses of existing hybrid topologies. Contrary to the dominant existing practice, a switchedcapacitor converter and a resistorless LDO operate in a parallel ...

A Low-Voltage, Low-Power, Two-Stage Amplifier for Switched-Capacitor Applications in 90 nm CMOS Process

Abstract- A novel low-voltage two-stage operational amplifier employing resistive biasing is presented. This amplifier implements neutralization and correction common mode stability in second stage while employs capacitive dc level shifter and coupling between two stages. The structure reduces the power consumption and increases output voltage swing. The compensation is performed by simple mill...
