| 摘 要： | A resistorless CMOS current reference is presented.Temperature compensation is achieved by subtracting two sub-currents with different positive temperature coefficients.The circuit has been implemented with a Chartered0.35μm CMOS process.The output current is 1.5μA,and the circuit works properly with a supply voltage down to 2 V.Measurement results show that the temperature coefficient is 98 ppm/℃,and the line regulation is 0.45%/V.The occupied chip area is 0.065 mm~2.
