The effects of fluorination on amorphous indium gallium zinc oxide thin-film transistors and circuits fabricated a polyimide flexible substrate were studied. Attributed to more effective passivation donor defects for given thermal budget, resulted in suppressed apparent short-channel better uniformity turn-on voltage with reduced negative shift after laser lift-off from glass carrier substrate....

A visible wavelength linear photosensor featuring a pixel size of 3mm has been designed for fabrication using commercial 0.25 mm CMOS technology. For the photo-sensing element, the design uses a special ‘‘deep N-well’’ in P-epi diode offered by the foundry for imaging devices. Pixel reset is via an adjacent p-FET, thus allowing high reset voltages for a wide pixel voltage swing. The pixel volta...

This paper focuses on the DC noise margin analysis and read/write failure analysis of the proposed 8T low power SRAM cell. In the proposed structure two voltage sources, one connected with the Bit line and the other connected with the Bit bar line for reducing the voltage swing during the switching activity.

Current mirror (CM) is the basic building block in analog and mixed mode circuit design. For high performance analog circuit applications, the current transfer ratio, output impedance and output swing are the most important parameters to determine the performance of the current mirror. CM’s are important for analog integrated circuits because of their wide use as constant sources or active load...

Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...

AbstractIn this paper, a low-voltage current mirror with neuron MOSFETs is proposed. The proposed circuit can decrease a variation of an output current of the current mirror by monitoring an error of the output current caused by the mismatch of MOSFETs. In addition, the proposed circuit can avoid a trade-off between an accuracy and an output swing. The proposed circuit is fabricated in phenitec...

Transmitters are used to pass data stream through transmission lines in either current or voltage mode. In high data rate applications, the output impedance of transmitters should match the transmission lines’ characteristic impedance and should be tunable in order to compensate the process, voltage, and temperature variations. The multiplexing technique can be used to extend transmitters signa...
