Hi there,
I'm just reading the book "Microelectronic Circuits Fifth Edition" by Sedra/Smith about frequency response for amplifiers. An example shows how to find the DC-gain of an amplifier. The transfer function is (equation #1), which is on the form (equation #2).
The write then uses K as the DC-gain when s-->0 in the transfer function (equation 3). But K is not the DC-gain, but a constant. The DC-gain is the result from (equation 3), when K is known. Right? And how to find K then? One must be known...?
Thanks
