3 ppm Ultra Wide Range Curvature Compensated Bandgap Reference
In this report a current mode bandgap with a temperature coefficient of 3 ppm for the range from -117◦C to 144◦C is presented. 2nd order curvature compensation is used by using a third BJT with a temperature constant current and a second error amplifier to get a nonlinear temperature coefficient current in extra to enhance the accuracy. The required minimum supply voltage is 1.3V for 3ppm and 1...
متن کاملA new curvature-corrected CMOS bandgap voltage reference
The current paper presents an improved bandgap voltage reference (BGR) that utilizes curvature-corrected current generators which compensate for the voltage reference at lower and higher temperature range. The voltage reference is operated with a supply voltage of 2.5V to achieve an output reference of 1.1835V. The temperature coefficient achieved from the circuit is 1.342 ppm/◦C, resulting fro...
متن کاملAdvances in Radio Science A curvature-corrected CMOS bandgap reference
This paper presents a CMOS bandgap reference that employs a curvature correction technique for compensating the nonlinear voltage temperature dependence of a diode connected BJT. The proposed circuit cancels the first and the second order terms in the VBE(T ) expansion by using the current of an autopolarized Widlar source and a small correction current generated by a MOSFET biased in weak inve...
متن کاملAn improvement of a piecewise curvature-corrected CMOS bandgap reference
In the current paper, an improvement of piecewise curvature-corrected CMOS bandgap reference (BGR) circuit is proposed. The circuit utilizes piecewise nonlinear curvature-corrected current (PNCCC) in a conventional BGR with a current control circuit, which compensates for the voltage reference at a higher temperature range. The current control circuit (CCC) is used to reduce the total current a...
