ABSTRACT:
A resistance compensation circuit and a method thereof for tuning frequency, includes several resistors serially connected to one another, several transistors, each of which connects across one of the corresponding resistances, and a register electrically connected to the gates of the transistors. A control signal controls the switching of the transistors either to compensate the process variation of the resistance through the register or to tune the working frequency of the Integrated circuit.
