摘要/Abstract

摘要： 提出了一种带有温漂修调电路的二阶曲率补偿带隙基准电压源。采用V_BE线性化补偿原理,通过在特定支路上产生二阶正温度系数电流来补偿V_BE的二阶负温度系数项,从而大大提高了基准电压的温漂特性。另外,设计了电阻修调电路,简化了修调方式,降低了设计难度和设计成本,并且保证了基准电压的高精度。电路基于TSMC 0.18 µm BCD工艺设计,使用Cadence Spectre对电路进行仿真验证,仿真结果表明,在3.3 V电源电压下,基准输出电压约为1.22 V,在-55~125 ℃温度范围内,温度系数为3.02×10^_6/℃,低频时电源电压抑制比为_51.21 dB。

Abstract: A second-order curvature compensation bandgap reference voltage source with temperature drift trimming circuit was proposed. Based on the principle of VBE linearization compensation, the temperature drift characteristic was greatly improved by generating a branch current with the positive temperature coefficient to compensate the negative temperature coefficient of nonlinear terms of VBE. In addition, the trimming resistance circuit was designed to simplify the trimming mode, reduce the design difficulty and cost, and ensure the high precision of reference. The circuit was designed based on TSMC 0.18 µm BCD process. And the circuit was simulated and verified by using Cadence Spectre. The simulation results showed that the reference output voltage was about 1.22 V at the power supply of 3.3 V and the temperature coefficient of the voltage reference was 3.02 ×10^_6 /℃ in the range of -55-125 ℃. Furthermore, the power supply rejection ratio was _51.21 dB at low frequency.

Key words: band-gap reference, second-order curvature compensation, temperature coefficient, power supply rejection ratio
