梯型网络的有源模拟是近年来受到重视的有源滤波器实现方法之一,这是因为比起其它结构的有源电路,梯型网络具有最好的通带元件灵敏度特性。从原理上说,梯型网络的有源实现方法可分为元件模拟和运算模拟。元件模拟就是指以有源的方法直接去模拟无源LC网络中体积大、造价高的电感元件;而运算模拟则是指用特定的有源方框电路去模拟梯型网络中的电压电流运算关系。
Active modeling of ladder networks is one of the most important active filter implementations in recent years. This is because ladder networks have the best sensitivity characteristics of passband components over active circuits in other architectures. In principle, the active realization of ladder network can be divided into component simulation and operational simulation. Component simulation refers to the active method to directly simulate large-scale, high-cost inductive components in a passive LC network. Computational simulation refers to using a specific active block circuit to simulate the voltage-current operation in a ladder network relationship.
