摘要：In this paper after a survey on base structure of band gap references, the nonlinear property of VBE and its effect on thermal dependency in bandgap references has been discussed. Furthermore, one of the main methods of curvature correction has been investigated by using mathematical computations. The mathematical and circuit simulations have been implemented in MATLABR2007 and ADS2006, respectively. A corrected modified criterion has then been suggested to minimize the curvature of VBE by using the best available resistors according to the thermal variations of the collector currents. Accuracy of the introduced criterion has been confirmed by applying circuit simulations.
