The exponential behaviour of the voltage-to-current characteristic is of primary importance because it enables us to construct a current source, which delivers a current that is proportional to the absolute temperature (PTAT). This can be used to implement a mechanism of temperature compensation in a bandgap reference circuit [8]. The conventional diode has an exponential voltage-to-current rel...

This paper proposes a low voltage CMOS nano-ampere current reference circuit and presents its performance with circuit simulations in 180-nm technology. The proposed circuit consists of biasvoltage, current-source and offset-voltage sub-circuits with most of MOSFETs operating in subthreshold region. Simulation results show that the circuit generates a stable reference current of 110-nA in suppl...

This paper presents the three topologies of three-phase four-wire DSTATCOM for reduction of harmonics, reactive power compensation, increasing power factor, which occur due to a nonlinear load, environment problem and polluted grid. The performances of the above topologies have been compared for the magnitude of source current, power factor improvement, DC-link voltage regulation, and total har...

A modified circuit topology for voltage references capable of providing very high load current with low-temperature-sensitivity output voltage is presented. Employing a proportional-to-absolute-temperature current source and a complementary-to-absolute-temperature voltage source in a novel closed-loop configuration, the output voltage can be tuned over a wide range of voltages lower or higher t...

this paper presents a new control method for a three-phase four-wire unified power quality conditioner (upqc) to deal with the problems of power quality under distortional and unbalanced load conditions. the proposed control approach is the combination of instantaneous power theory and synchronous reference frame (srf) theory which is optimized by using a self-tuning filter (stf) and without us...
