电子秤供桥电源的设计（续）张连儒，张旭明３．基准稳压源Ｂ的选择在供桥电源的设计中，基准稳压源的设计也是非常重要的。显而易见，如果稳压源的稳定性不好，通过放大器放大后的输出值就不可能稳定，供桥电源也不可能达到高稳定度。所以在设计时应选择温度系数、时漂、... Design of Electronic Scales for Bridge Power Supply (Continued) Zhang Lianru, Zhang Xuming 3. The choice of the reference voltage regulator B In the design of the bridge power supply, the design of the reference voltage regulator is also very important. Obviously, if the stability of the regulator source is not good, the output value amplified by the amplifier can not be stable, and it is impossible for the bridge power source to achieve high stability. Therefore, the design should choose the temperature coefficient, when the drift, ...
