Conversely, if the current through an ideal current source is determined by some other voltage or current in a circuit, it is called a dependent or controlled current source.
相反，如果其他一些电压或电路中的电流通过一个理想电流源的电流决定，它被称为从属或控制的电流源。
As the charge exerted from input voltage source is dependent on quantization error and input noise voltage to a large extent, the circuit has high signal input impedance.
由于提取自输入电压源的电荷很大程度上仅取决于量化误差与输入噪声电压，所以电路具有高信号输入阻抗。
