【 摘 要 】

References(5)We proposed a novel temperature-compensated, ultra-low-power current reference based on two β-multipliers whose resistors are replaced by nMOS devices operated in the deep triode region. The circuit, designed by a 0.25µm CMOS process, produces an output reference current of 13.7nA at room temperature. Simulated results show that the temperature coefficient of the output is less than 100ppm/°C in the range from -20°C to 80°C and the average power dissipation is 0.9µW.
