摘要：

In this paper, a low voltage high accuracy 10-transistor power-on-reset circuit with brown-out-reset function is proposed. A native NMOS current reference based architecture is proposed to get high accuracy trip-voltage with a small area and power consumption. By adjusting the number of native NMOS transistors, a stable hysteresis window is obtained. Post-layout simulation results based on SMIC 55nm CMOS process show that the trip-voltage deviation of the proposed power-on-reset circuit is only 34mV under different temperature and process corners. Also, the trip-voltage of the proposed power-on-reset circuit shows great robustness to supply ramp time. The power consumption of the proposed circuit is as low as 36nW at 0.5V. Since the proposed power-on-reset circuit consists of only 10 transistors, the area is as low as 67.5 mu m(2).
