This paper proposes a read-only memory driving circuit for RFID tags based on a-IGZO thin-film transistors. The circuit consists of a Johnson counter and monotype complementary gates. By utilizing complementary signals to drive a decoder based on monotype complementary gates, the propagation delay can be decreased and the redundant current can be reduced. The Johnson counter reduces the number of registers. The new circuit can effectively avoid glitch generation, and reduce circuit power consumption and delay.

A new sustain driving circuit, featuring an energy-recovering function with simple structure and minimal component count, is proposed as a cost-effective solution for driving plasma display panels during the sustaining period. Compared with existing solutions, the proposed circuit reduces the number of semiconductor switches and reactive circuit components without compromising the circuit performance and gas-discharging characteristics. In addition, the proposed circuit utilizes the harness wire as an inductive circuit component, thereby further simplifying the circuit structure. The performance of the proposed circuit is confirmed with a 42-inch plasma display panel.

This paper proposes the design of a driver to deal with a thin-disc central supporting structure ultrasonic actuator based on the vibration modes and the equivalent circuit. In order to gain the electromechanical match at resonant frequency, a spectrum analyzer should measure admittance for driving piezoelectric ceramics. The virtual analyzer also investigated the characteristics of a MODEL-E equivalent circuit based upon the admittance-frequency response. The inherent capacitance from an ultrasonic actuator became the partial component in the design of a resonant circuit. IsSpice software is introduced to simulate as well as the experimental results has demonstrated a high agreement related to the conceptual design and practical implementation for the driving circuit.

This paper deals with a method for designing the driving circuit of an electroluminescent (EL) element whose power consumption is lower and the deviation of output voltage is smaller even when the EL element is replaced with another of a different shape. In this driving circuit, an AC voltage raised by a step-up transformer is supplied to the EL element. The oscillation conditions in the orthodox driving circuits were theoretically analyzed, and a new driving circuit which incorporates these characteristics is proposed. A new prototype driving circuit taking the resonance characteristics between the capacitance of the element and the inductance of the transformer into consideration was made. In the experiment, an inorganic AC EL cable-type element was used as the load of the driving circuit as its impedance can be easily adjusted by changing its length. In comparison with orthodox circuits, the power consumption was lower and the changes in the output voltage were smaller in the new prototype circuit even when the changes in the impedance were large.
