摘要:
The present invention includes: a temperature compensation circuit for generating a digital signal corresponding to a temperature of a transistor and outputting a compensation bias current obtained by adding a control current to a reference bias current or by subtracting the control signal from the reference bias current using the generated digital signal; a characteristics compensation circuit for detecting a characteristics error of a mirror transistor connected to the transistor in parallel and for outputting a compensation signal to compensate the characteristics error; and a bias compensation circuit for compensating a bias power applied to the transistor using the compensation bias current and the compensation signal to output the compensated bias power. The present invention is capable of improving the performance of the transistor.
