The invention provides a CMOS GOA circuit, by disposing a feedback regulation module (4) connected to output buffer module (3) and signal processing module (2) in the GOA unit, to achieve the following: when the scan driver signal (G(N)) becomes high, the positive feedback from the sixth N-type TFT (T6) of feedback regulation module (4) will enhance the pull-down capability of the signal processing module (2) to reduce the rising time of the scan driver signal (G(N)) waveform; when the scan driver signal (G(N)) becomes low, the positive feedback from the fifth P-type TFT (T5) of feedback regulation module (4) will enhance the pull-up capability of the signal processing module (2) to reduce the falling time of scan driver signal (G(N)) waveform; that is, the invention can reduce the RC loading of scan driver signal (G(N)) and improve the stability of high resolution display panel.
