Description

technical field [0001] The invention relates to the field of semiconductor integrated circuits, in particular to an output feedback logic circuit and chip based on unipolar transistors. Background technique [0002] Practical difficulties exist between traditional rigid electronics and bendable everyday objects such as paper, tape, human body, and textiles. We can solve this problem with large-area flexible electronics. These large-area flexible electronics technologies offer bendability, light weight, ultrathin size, transparency, stretchability, large-area applicability, low cost, and several other attractive features. [0003] However, most current flexible electronic technologies can only provide high-performance unipolar (pure n-type or pure p-type) devices. For example, in a-Si TFT technology, the main device type of oxide TFT technology is n-type transistor; while in organic TFT technology, the main device type of carbon nanotube technology is p-type transistor.

Problems solved by technology

From the perspective of circuit complexity, the pseudo-CMOS technology requires two power supplies, and the capacitor bootstrap technology requires a bootstrap capacitor, which undoubtedly increases the circuit complexity.

From the perspective of power consumption, when the input is high, neither the pull-up transistor nor the pull-down transistor can be completely turned off, so there is a large leakage current, resulting in non-zero static power consumption
