Performance of the Bandgap Reference Circuit, designed in a commercial 0.13um CMOS
نویسنده
چکیده
The exponential behaviour of the voltage-to-current characteristic is of primary importance because it enables us to construct a current source, which delivers a current that is proportional to the absolute temperature (PTAT). This can be used to implement a mechanism of temperature compensation in a bandgap reference circuit [8]. The conventional diode has an exponential voltage-to-current relationship above 650mV while the DTMOST device is exponential within a region from 100mV to 220mV (see Fig.3).

Sub-1-V-Output CMOS bandgap reference circuit with small area and low power consumption
In this paper, a new low-VDD CMOS bandgap reference circuit with small layout area and low power consumption is proposed. The proposed circuit delivering its output voltage below 1V has its Proportional-To-Absolute-Temperature (PTAT) term compensated by the Complementary-proportional-To-AbsoluteTemperature (CTAT) voltage thereby suppressing a change in its output voltage regardless of temperatu...
