一种带曲率补偿的低温漂低功耗带隙基准源设计
Design of low temperature drift and low power consumption bandgap reference source with curvature compensation
摘要
Abstract
Based on OKI 0.5μm BCD process, a low temperature drift and low power consumption bandgap reference voltage source with curvature compensation was designed. With traditional amplifier clamping method, a quasi exponent property current was added up the core part of the reference to achieve curvature compensation effect. Simulation results show that under the power supply voltage of 5 V from 223 K to 423 K, the output reference voltage range is from 1.175 V to 1.182 V, with a temperature drift of about 2.15×10–6/K. The power supply rejection ratio (PSRR) is–64 dB when the reference source is high precision and low frequency;the static current of the reference source is only 5.6μA.关键词
