摘要

为了对薄膜晶体管液晶显示器（TFT-LCD）驱动芯片的驱动电压进行温度补偿以改善TFT-LCD的性能，本文基于标准CMOS（3.3 V）的chrt35rf 0.35 μm工艺，设计了一款温度系数可连续调节的带隙基准电压源，其中包括核心电路、运算放大器电路和启动电路3个子模块。该电路使用MOS晶体管作为可变电阻，通过调节MOS栅极电压控制MOS漏源等效电阻的连续可变，进而改变电路中的电阻比值，实现带隙基准源的温度系数连续可调。使用Cadence的Spectre仿真器进行仿真，结果表明，在-25~125℃的工作温度范围内，带隙基准源电路的输出电压的正温度系数可连续调节范围为156.6~2 545.0 ppm/℃，输出电压的负温度系数的连续变化范围为156.6~1 337.7 ppm/℃，输出基准电压变化为0.95~2.67 V，低频时基准电压的电源抑制比达到73.13 dB。该电路实现了基准电压从负温度系数向正温度系数的连续可调节，且调节范围较大。

Abstract

In order to compensate the driving voltage of driver chip of thin-film-transistor liquid crystal display(TFT-LCD) to improve the performance of TFT-LCD

in this paper

based on the standard CMOS (3.3 V) chrt35rf 0.35 m process

a bandgap reference circuit with continuously adjustable temperature coefficient is designed. The circuit includes three sub-modules of a core circuit

an operational amplifier circuit

and a startup circuit. Using a MOS transistor as a variable resistor

the source-drain equivalent resistance of MOS can be changed continuously by the gate voltage. Then

the temperature coefficient of the bandgap reference can be adjusted continuously by changing the resistance ratio in the circuit. The designed circuit is simulated by the Cadence Specter simulator. The results show that in the working temperature range from -25 to 125℃

the positive temperature coefficient

negative temperature coefficient

and output voltage are 156.6~2 545.0 ppm/℃

156.6~1 337.7 ppm/℃

and 0.95~2.67V

respectively. The power supply rejection ratio(PSRR) of the reference voltage at low frequencies reaches 73.13 dB. The circuit achieves continuous adjustment of the reference voltage from negative temperature coefficient to positive temperature coefficient. In addition

the adjustment range of temperature coefficient is large.
