A new TN-ECB mode liquid crystal display is developed for reflective liquid crystal displays (RLCDs). This new TN-ECB mode has a larger cell gap and lower operating voltage than most recently developed RLCDs. It also has a small wavelength dispersion and has a good dark state at the low operating voltage. It is particularly suitable for reflective crystalline Si backplane CMOS AMLCDs.

A simple analytical model has been developed to optimize biasing conditions for obtaining maximum linearity among lattice-matched, pseudomorphic and metamorphic HEMT types as well as enhancement and depletion HEMT modes. A nonlinear current-voltage model has been simulated based on extracted data to study and select the most appropriate type and mode of HEMT in terms of a given gate-source bias...

This paper deals with new hybrid multilevel inverter fed induction motor drive. It focuses on the different topologies to mitigate the common mode voltages, bearing currents and their effects on the drive. In proposed topology, the total harmonic distortion (THD) is reduced with more number of steps in output voltage without using pulse width modulation techniques. The main advantage of this pr...

Abslrad : Some practical methods --r implementing the sliding-mode control law to control the buck-type converters are introduced. The control equations are derived from the basic slidmg-mode control law to accommodate the conventional fiied-frequency pwm control method. As a result, the overall feedback control systems can be expressed under a form similar to state-feedback control where the v...

The topology and control are discussed of a distribution static compensator (DSTATCOM) that can be operated flexibly in the voltage or current control mode. In the voltage control mode, the DSTATCOM can force the voltage of a distribution bus to be balanced sinusoids. In the current control mode, it can cancel distortion caused by the load, such that current drawn by the compensated load is pur...

A new voltage-mode triple-input single-output multifunction filter using only two current conveyors is presented. The proposed filter which possesses three inputs and single-output can generate all biquadratic filtering functions at the output terminal by selecting different input signal combinations. The validity of the proposed filter is verified through PSPICE simulations. Keywords—Active Fi...

This paper presents some aspects of building reprogrammable system using current mode gates. With this approach it is possible to extend system on a chip solutions into the area of mixed mode applications. CMOS current mode gates consume almost constant current from the power supply and therefore are suitable for mixed mode operations. Contrary to voltage mode digital gates, presented in the pa...
