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...

Electrical Engineering (ABSTRACT) The conventional power factor correction circuit has a fixed output voltage. However, in some applications, a PFC circuit with a wide output voltage range is needed. A single phase power factor correction circuit with wide output voltage range is developed in this work. After a comparison of two main power stage candidates (Buck+Boost and Sepic) in terms of eff...

A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...

In this study, the noise voltage on the circuit installed in the frame caused by the ground potential variation and the influence of the resistance of the frame ground on the noise voltage on the circuit are discussed. It is concluded as a result of measurement and circuit simulation that the noise voltage gets lower as the grounding resistance becomes high and the capacitive coupling between t...
