如果我们实际量到一个Low Noise Amplifier 增益为28dB,噪声指数为2dB,我们可以有两个系统模型Model 1就是一般课本常见模型,Model 2是我们用一个理想的放大器与一个衰减器来组成,两个都会得到一样的结果 Gain = 28dB,NF = 2dB,两个在系统上是分不出差异。
Question: For the amplifier shown below figure, calculate the gain in dB at a frequency of two times the pole frequency by neglecting channel length modulation (a = 0) and all other capacitances. (use exact calculation not asymptotic approach) Circu...

by detecting the output level of the analog signal input from the sound source via a digital -to-digital converter each source coded , each with different volume setting for optimal default amplifier gain , and the phone set to the output amplifier for amplifying and outputting the gain control...
The classical definition of slew rate in high open loop gain op amp type products and still an important distinction, is true slew rate limiting comes along with the feedback loop opening up as the output cannot keep up with the signal demands. Driving larger and larger steps at the output...
