The effects of error sources which may affect the performance of the voltage reference are analyzed and minimized. Simulation results in the TSMC 180nm process show that the design can achieve temperature coefficients of less than 0.85ppm/°C across process corners and local random ...
High PSRR is achieved by means of introducing dual PSRR enhancement stages which isolate the bandgap voltage from the variations and noise of the power supply. A temperature coefficient of 5.5ppm/°C is achieved over a temperature range of 0–125°C, and the power consumption of the circuit ...
A new sub-1-ppm/°C curvature-compensated bandgap voltage reference (BGR) is presented in this paper. The Complementary to Absolute Temperature (CTAT) voltage component of a forward biased BJT is first well balanced with a Proportional to Absolute Temperature (PTAT) voltage, leaving only a hig...
minimum TC of only 0.42 ppm/°C under a wide temperature range, hence it can provide multiple high-precision output voltages for data converter in sensor interface applications. The BGR is designed to work under 5V supply with 2.5V output reference voltage for the requirement of the sensor it...
