COMPENSATION CIRCUIT FOR COMMON VOLTAGE ACCORDING TO GATE VOLTAGE |
摘要 |
Disclosed is a compensation circuit for a common voltage according to a gate voltage, which compensates the common voltage in accordance with variation in gate high voltage, to obtain an optimal common voltage. The compensation circuit includes a divider to divide a gate high voltage, an adder to add a fed-back common voltage to a voltage output from the divider, and a differential amplifier to differentially amplify a voltage output from the adder, and to output the amplified voltage as a compensated common voltage. |
