摘要:
An analog buffer circuit for a liquid crystal display (LCD) device includes a first capacitor and an inverter connected in series between an input terminal and an output terminal, a first reset switch connected between the input terminal and the first capacitor to reset the first capacitor, a first feedback switch connected to a first node between the first capacitor and the first reset switch, a second capacitor and a second feedback switch connected in series between a second node and a third node, the second node connected between the first capacitor and the inverter, and the third node connected between the inverter and the output terminal, a second reset switch connected between the second node and the third node to reset the inverter, and a third reset switch connected to a fourth node between the second capacitor and the second feedback switch to reset the second capacitor.
