Before revision: This form is: where the so-called asymptotic gain G∞ is the gain at infinite gm, namely: and the so-called feed forward or direct feedthrough G0 is the gain for zero gm, namely: For additional applications of this method, see asymptotic gain model .
After revision: and Blackman's theoremThis form is: where the so-called asymptotic gain G∞ is the gain at infinite gm, namely: and the so-called feed forward or direct feedthrough G0 is the gain for zero gm, namely: For additional applications of this method, see asymptotic gain model .
