In this paper a novel very high performance current mirror is presented. It favorably benefits from such excellent parameters as: Ultra high output resistance (36.9GΩ), extremely low input resistance (0.0058Ω), low output (~0.18V) and low input voltage (~0.18V) operation, very low power consumption (20μW), very low offset current (1pA), ultra wide current dynamic range (150dB), and ultra high a...

Efficiency aggregation and efficiency decomposition are two techniques used in modeling decision making units (DMUs) with two-stage network structures under network data envelopment analysis (DEA). Multiplicative efficiency decomposition (MED) is usually used in a very specialized two-stage structure when constant returns to scale (CRS) is assumed. MED-based network DEA retains the property of ...

This paper presents the high-output-impedance current-mode multiphase sinusoidal oscillators (MSO) using voltage differencing current conveyor (VDCC)-based lossy integrators, which consist of one VDCC, grounded capacitor, and two resistors. The proposed oscillator can provide an odd-phase even-phase system without use additional amplifier. frequency oscillation (FO) is electronically tuned via ...

A 1.227 GHz low power single-ended input, differential output low noise amplifier (balun LNA) for GPS is proposed. A two stage structure with current-reused technique is adopted to achieve low power, low noise factor and high voltage gain simultaneously. The LNA is fabricated in 0.18 mm CMOS process, consuming only 2 mA current from a 1.8 V supply. The LNA is measured to exhibit a differential ...

This paper describes the three-phase grid-connected inverter model for photovoltaic application. The inverter system model and control strategies are carried in MATLAB/SIMULINK environment. Utilizing both proportional-integral controllers for the control loops, and the sinusoidal pulse-width modulation switching signals generation technique for the IGBTs, the inverter control system capable of ...

This study presents a high-efficiency low-noise pulse-width modulation (PWM) DC–DC buck converter based on multi-partition switching for mobile system-on-a-chip applications. A multi-partition switching technique is employed for the control of large current driving switches to minimise the switching noise. In addition, a PWM control with a switching frequency of 2 MHz is applied for the driving...

A low-voltage low-dropout (LDO) regulator that converts an input of 1 V to an output of 0.85–0.5 V, with 90-nm CMOS technology is proposed. A simple symmetric operational transconductance amplifier is used as the error amplifier (EA), with a current splitting technique adopted to boost the gain. This also enhances the closed-loop bandwidth of the LDO regulator. In the rail-to-rail output stage ...
