A low voltage CMOS constant current-voltage reference circuit
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004 The proposed CMOS current-voltage reference circuit consists of a traditional bandgap circuit based on the use of PMOS transistors in weak inversion. Its current is stabilized by an on-chip resistor with positive temperature coefficient. The voltage reference is produced by compensating the positive temperature coefficient of a resistor by the negative
