Background/Objectives: Density, performance, and design complexity of integrated circuits are rapidly increasing specifically in 3-D integration where multi-plane synchronization is required. The power clock distribution networks consume a large portion the limited on-chip metal resources. In order to reduce overhead associated with power, global clock, local networks, concept an network (IPCDN...

The idea that dorsal thalamic inputs can be divided into "drivers", which provide the primary excitatory drive for the relay of information to cortex, and "modulators", which alter the gain of signal transmission, has provided a valuable organizing principle for the study of thalamic function. This view further promoted the identification of "first order" and "higher order" thalamic nuclei, bas...

Design automation of LCD driver circuits is not sophisticatedly established. Display fineness of an LCD panel depends on a performance metric, ratio of pixel voltage to video voltage (RPV). However, there are several other important metrics, such as power consumption and area, and the best circuit cannot be decided uniquely. This paper proposes a design automation technique to provide several c...

This paper presents a survey of some of the most aggressive custom designs for CMOS processor products and prototypes in IBM. We argue that microprocessor performance growth, which has traditionally been driven primarily by CMOS technology and microarchitectural improvements, can receive a substantial contribution from improvements in circuit design and physical organization. We predict that in...

A stimulus driver circuit for a micro-stimulator used in an implantable device is presented in this paper. For epileptic seizure control, the target of the driver was to output 30 µA stimulus currents when the electrode impedance varied between 20 and 200 kΩ. The driver, which consisted of the output stage, control block and adaptor, was integrated in a single chip. The averaged power consumpti...

In this this paper, an IP driver block was designed and simulation conducted for an AMOLED display which supplies power as selected by users. The IP driver design focused on the regulation of output power, due to the OLED characteristic for diode electric current according to voltage, to be activate by pulse-skipping mode (PSM) under low loads, and 1.5 MHz pulse-width modulation (PWM) for mediu...

A new type of drivers for light emitting diodes (LEDs) is introduced based on the switched-capacitor frequency modulation. In contrast to conventional constant dc current drivers, the current pulse is provided by this new switched-capacitor LED driver. In the present driver, the charging capacitor is charged and discharged through a LED and the current flow direction is controlled by a metal ox...

A shift in consumer electronics from analog to digital technology is underway, and the television industry is transitioning from CRT to flat panel display (FPD) technology. With the increasing popularity of FPDs, the market for plasma display panels (PDPs) has also grown rapidly. The FPD market is divided according to screen size: sizes of 30 inches and smaller use liquid crystal display (LCD) ...

A new source follower circuit using low-temperature polycrystalline silicon thin film transistors (LTPS-TFTs) as analog buffer for the integrated data driver circuit of active matrix liquid crystal displays (AMLCDs) and active matrix light emitting diodes (AMOLEDs) is proposed and measured. Threshold voltage compensation circuit with two n-type thin film transistors, a capacitor, and four switc...
