Abstract
A terminal correction circuit includes a first terminal replica model, a terminal voltage offset correction circuit, a second terminal replica model and a terminal resistance offset correction circuit. The first terminal replica model sets a resistance ratio of first and second adjustable resistors according to a voltage correction code, thereby adjusting a terminal voltage. The terminal voltage offset correction circuit compares the terminal voltage and a third power supply voltage and provides the voltage correction code according to the comparison result. The second terminal replica model sets a resistance ratio of third and fourth adjustable resistors according to the voltage correction code and reduces an equivalent resistance value between a half-voltage terminal and a ground voltage according to a resistance correction code. The terminal resistance offset correction circuit compares a comparison voltage with a second power supply voltage and provides the resistance correction code according to the comparison result.
