【Abstract】 The circuit that can work in the low voltage condition is needed when the process improves and the power supply decreases. In this paper,a clock generator circuit that can work in the 1.8 V condition is introduced. Its frequency decreases as the power supply increases as the temperature increases. And it can suppress the process variation so that the output voltage of the chargepump can be stabilized.更多还原
