A CMOS current-mode S-shape correction circuit with shape-adjustable control is proposed for suiting different LCD panel's characteristics from different manufactures. The correction shape is divided into three segments for easy curve-fitting using three lower order polynomials. Each segment could be realized by a corresponding current-mode circuit. The proposed circuit consists of several control points which are designed for tuning the correction shape. The S-shape correction circuit was fabricated using the 0.35µm TSMC CMOS technology. The measured input dynamic range of the circuit is from 0µA to 220µA. The -3dB bandwidth of the circuit is up to 262MHz in a high input current region.
