Dual-Band Voltage-Controlled Oscillator for CB and HF RFID Bands in a Flexible IGZO Technology

Dual-Band Voltage-Controlled Oscillator for CB and HF RFID Bands in a Flexible IGZO Technology 150 150
Author(s): Lautaro N. Petrauskas, Bahman K. Boroujeni, Frank Ellinger

Abstract:

In this work, a cross-coupled voltage-controlled oscillator (VCO) for the high frequency RFID and citizen bands (CBs) is investigated, and implemented on a flexible Indium gallium zinc oxide thin film transistor (TFT) technology. To circumvent the challenges of integrating passive components in this frequency range and minimize the circuit’s …

A High-Speed D-FF and a 11-Bit Up-Down Counter Using Unipolar Oxide TFTs on a Flexible Foil

A High-Speed D-FF and a 11-Bit Up-Down Counter Using Unipolar Oxide TFTs on a Flexible Foil 150 150
Author(s): Suyash Shrivastava, Pydi Ganga Bahubalindruni

Abstract:

This manuscript presents an experimental characterization of a novel high speed D flip-flop (D-FF). The circuit was fabricated on a $27\mu $ m thick flexible polyimide substrate using a nMOS only, single gate amorphous Indium-Gallium-Zinc-Oxide (a-IGZO) thin-film transistor (TFT) technology. Reliable response of the D-FF was noticed from measurements up to …

An Area and Power Efficient Source Driver IC With Multi-Line Sensing Real-Time Pixel Compensation for OLED Displays

An Area and Power Efficient Source Driver IC With Multi-Line Sensing Real-Time Pixel Compensation for OLED Displays 150 150
Author(s): Jaewoong Ahn, Seung Hun Choi, Minseong Um, Jun Yeol An, Hyung-Min Lee

Abstract:

This article proposes a source driver integrated circuit (SD-IC) with a pixel compensator designed to minimize both silicon area and power consumption for organic light-emitting diode (OLED) displays. The proposed SD-IC is capable of driving ultrahigh-definition (UHD) active-matrix OLED (AMOLED) panels with a one-horizontal-time (1-H time) of $7.2~\mu $ s while …
