I was studing about baising in general (irrespective if it is for BJt or MOS) and just looking at the graph i had several questions. I know the basic concept, the amplifiers, +ve and -ve saturation limits causes the signal outside the limit to truncate. to ensure that the signale should not truncate, we need to determine the range of input signals. Also in order to get the linear relation between input and output we need to select the range. We bias the circuit to ensure that the signal is within the range and we is within the linear region. My qestion is, does biasing depend on the signal frequency? Does it changes for signals with higher frequency and signals with lower frequency? Also, I would really appreciate if you could help me in explaining how you got the results? which books did u refer or what logic did you follow. Thanks, Regards!!!
