Common gate transistors, integrated circuits and electronic devices

Abstract

The invention provides a common-gate transistor, an integrated circuit and an electronic device. The common-gate transistor includes five transistors whose gates are connected to each other from the first to the fifth transistors. The gate layers of these five transistors are connected to form a single A gate pattern, and the circuit nodes where the drains of the second and fourth transistors are connected to the source of the first transistor and the circuit nodes where the sources of the third and fifth transistors are connected to the drain of the first transistor are all Located under the gate pattern, thereby reducing the layout area of ​​these five transistors, the integrated circuit based on the common gate transistor can greatly save the circuit layout design space and layout design difficulty, which is conducive to the display of high PPI devices and other highly integrated electronic device designs.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a common gate transistor, an integrated circuit and an electronic device. Background technique [0002] In circuit design, a common-gate transistor is a common transistor group structure, which includes more than two independent transistors, and the gates of these transistors are electrically connected to each other. However, the existing common-gate transistors have the problem of occupying too much layout space in the layout design, which is not conducive to improving the integration and performance of the circuit board. For example, in some current Active Matrix Organic Light Emitting Diodes (Active Matrix Organic Light Emitting In the pixel compensation circuit (such as 7T1C circuit structure) of Diode, AMOLED) display, the number of thin-film transistors (TFTs) is relatively large, and the common-gate transistors occupy a relatively large layout space in layout design, whic...
