长期以来电路系统中习惯以电压量作为研究和处理的对象,这就是大家熟悉的电压模电路,而另一类电路则以电流量作为研究和处理的对象,这就是电流模电路.电流模电路具有频带宽、速度高、动态范围大、非线性失真小等优点,因此近30年特别近几年里有了迅速发展.电流模电路种类很多,有互线性电路、电流放大器、电流传送器、开关电流电 For a long time the circuit system is accustomed to the amount of voltage as the object of study and processing, which is familiar with the voltage mode circuit, while the other type of circuit is the amount of current as the research and processing object, this is the current mode circuit. Current mode circuit With the advantages of wide frequency band, high speed, large dynamic range and small nonlinear distortion, the recent 30 years have witnessed rapid development especially in recent years. There are many types of current mode circuits, such as linear circuits, current amplifiers, current transmitters, Switching current
