Year: 2024

Type: article

Abstract: This paper introduces a multi-channel programmable gamma voltage generator. Based on the characteristics of the gamma curve, the gamma correction system applies a two-stage adjustment and a three-region output structure. The proposed programmable preset circuit allows the chip to deliver a programmable initial gamma. By integrating a transient enhancement circuit into the Class AB buffer, the amplifier achieves improvements of 27.8%/30.7% in undershoot/overshoot voltages, respectively. It also features a slew rate of 13.4V/µs, a 0.1% settling time of 0.62µs, and a DC gain of 138dB.
