A Low-Power Voltage Reference Cell with a 1.5 V Output

Abstract A low-power voltage reference cell for system-on-a-chip applications is presented in this paper. The proposed cell uses a combination of standard transistors and thick-oxide transistors to generate a voltage above 1 V. A design procedure is also presented for minimizing the temperature coefficient (TC) of the reference voltage. This circuit was fabricated in a standard 0.35 μ m complementary metal-oxide-semiconductor (CMOS) process. It generates a 1.52 V output with a TC of 42 ppm / ° C from ？70 ° C to 85 ° C while consuming only 1.11 μ W. View Full-Tex
