Title:
電圧バッファと電圧バッファのソースドライバ
Document Type and Number:
Japanese Patent JP4558701
Kind Code:
B2
Abstract:
A voltage buffer and the source driver thereof are disclosed. The above-mentioned voltage buffer includes an operational amplifier and an overdriving unit, wherein the operational amplifier outputs an output voltage. The overdriving unit is coupled between an input voltage and the operational amplifier for comparing the input voltage with the output voltage and outputting an overdriving voltage to the positive input terminal of the operational amplifier. Herein if the input voltage is greater than the output voltage, the overdriving voltage is greater than the input voltage; if the input voltage is less than the output voltage, the overdriving voltage is less than the input voltage; if the input voltage is equal to the output voltage, the overdriving voltage is equal to the input voltage.
