A low power, low temperature coefficient (TC) CMOS voltage reference generator is proposed in this paper, which exploits temperature mutual compensation relationship between threshold voltage and thermal voltage, and provides a mean reference voltage of 411.8mV.In this reference, a proportional to absolute temperature (PTAT) current containing the thermal voltage which has a positive TC is generated, and then it is injected into a diode-connected NMOS transistor that supply the threshold voltage which has a negative TC. The mixing of the two voltages produces a reference voltage with zero TC. The proposed circuit is verified by SPICE simulation with CMOS 0.18um process technology. The simulation results show that the power consumption is 17.9nW and the TC is 8.6ppm/øC. The proposed circuit is suitable for power sensitive applications.
