A 1.02 MHz 5.72-μW 60-ppm/°C relaxation oscillator is demonstrated in a 180-nm CMOS process. The proposed oscillator simplifies the logic control circuits to save power consumption and chip area. By employing an improved delay compensation technique, the proposed oscillator has minimized sensitivity to temperature variations. The measured results show an average frequency drift of about 60 ppm/°C and a power consumption of below 6 μW. For a supply voltage change of from 1.1V to 2 V, the frequency changes within only ± 1.6%.
