许多应用利用精密电流源提供恒定电流，包括工业过程控制、仪器仪表、医疗设备和消费电子产品。例如，过程控制系统利用电流源提 供电阻温度检测器(RTD) 所需的激励电流；数字万用表利用电流源测量未知电阻、电容和二极管；长距离信息传输广泛使用电流源 ...

噪声重要与否，取决于它对目标电路工作的影响程度。 例如，一个开关电源在3 MHz时具有显著的输出电压纹波，如果它为之供电的电路仅有几Hz的带宽，如温度传感器等，则该纹波可能不会产生任何影响。但是，如果该开关电源为RF锁相环(PLL)供电，结果可能大不 ...

Comparator ICs are designed to compare the voltages that appear at their inputs and to output a voltage representing the sign of the net difference between them. In a comparator circuit, if the ...
