Microgrids are nowadays used to produce electric energy with more efficiency and advantage. However, the use of microgrids presents some challenges. One of the main problems of the microgrids widely used in electrical power systems is the control of voltage, frequency and load sharing balance among inverter- based distributed generators (DGs) in islanded mode. Droop method performance degra...

This paper presents a new circuit arrangement for a current-mode Wheatstone bridge that is suitable for low-voltage integrated circuits implementation. Compared to the other proposed circuits, this circuit features severe reduction of the elements number, low supply voltage (1V) and low power consumption (<350uW). In addition, the circuit has favorable nonlinearity error (<0.35%), operate with ...

This paper presents the design of a Current-toVoltage (I−V) and Voltage-to-Current (V−I) converters for use in current-mode analog integrated circuits are described. The proposed I−V converter and V-I Converter has high linear range. The circuit uses MOS transistors in linear and saturation regions to produce an output current linearly related to the input voltage. Both circuits have been imple...

In this paper, we propose the use of second-order slope compensation for a current-mode PWM buck converter. First, the current feedback loop in a current-mode PWM buck converter using a conventional slope compensation is analyzed by the small-signal transfer function. It becomes clear that the stability and frequency bandwidth of the current feedback loop is affected by the external input volta...

a log-domain current-mode true rms-to-dc converter based on a novel synthesis of a simplified current-mode low pass filter and a two-quadrant squarer/divider is presented. the circuit employs floating gate mos (fg-mos) transistors operating in weak inversion region. the converter features low power(<1.5uw), low supply voltage (0.9v), two quadrant input current, immunity from body effect, low ci...

A novel mixed mode current and dynamic voltage CMOS 1-bit full adder cell is presented. In this new design, by combination of voltage and current mode circuits and adopting the advantage of each circuit in the finest way, we obtain the highest possible speed. The results are validated through HSPICE Simulation with 0.18 um and 1.8v, Vdd.
