标题[理工] [电子]-运算放大器的频率响应
时间Thu Feb 4 12:32:00 2010
有一题如下
An Amplifier with inverting circuit intended for very-high frequency operation
yet characterized by a single-pole roll-off,has ft=100MHz and Ao=20v/v.
For a design in which theh th actual(rather than the nominal) closed-loop
gain is -10v/v.
What 3db frequency results?
请问各位这题如何解呢?
感谢
