Abstract

The present invention provides systems, methods and apparatus for all n-type transistor inverter circuits. The circuit may include an input thin film transistor TFT, a pull-down TFT, a discharge TFT, a first pull-up TFT, a second pull-up TFT, and a floating capacitor. The circuit may also include first and second low voltage voltage sources and first and second high voltage voltage sources. The TFT, the capacitor and the voltage source may be coupled such that the output of the circuit is the logical inverse of the input of the circuit. In some implementations, the circuit can exhibit zero DC current in two logic states and can output a voltage substantially equal to the voltage output by the first low voltage voltage source and the second high voltage voltage source. In some implementations, the circuits can be used to construct D flip-flops, buffers, and controllers for active matrix electronic displays.

Description

[0001] Related applications [0002] This patent application claims U.S. Utility Application No. 13 entitled "ALL N-TYPE TRANSISTOR INVERTER CIRCUIT" filed on July 9, 2013 and assigned to the present assignee and is hereby expressly incorporated by reference herein. / Priority No. 937,752. technical field [0003] The present invention relates to semiconductor circuit design, and in particular, to all n-type transistor circuits. Background technique [0004] Current thin film metal oxide semiconductor (MOS) circuits (eg, indium gallium zinc oxide (IGZO) based circuits) suffer from the lack of readily available p-mos transistors. Also, common complementary metal-oxide-semiconductor (CMOS) digital circuits (eg, inverters, buffers, and various logic gates) available in common silicon circuits cannot be used in metal-oxide thin-film based processes. It has been proposed to replace such CMOS components with circuits made all n-type transistors, but almost, if not all, have var...
