DN, 2020 V.T.M Amplifier Characteristics  Ideally, we would like that the output of an amplifier be a linear function of the input, i.e., the input times a constant gain: 𝑦 𝑡 = 𝛼0 + 𝛼1 𝑥(𝑡) y 𝛼0 x  In real world the input-output characteristics is typically a nonlinear function: 𝑦(𝑡) = 𝛼0 + 𝛼1 𝑥(𝑡) + 𝛼2 𝑥 (𝑡) + ⋯ + 𝛼𝑛 𝑥 𝑛 (𝑡) DN, 2020 V.T.M Analog Design Trade-offs DN, 2020 V.T.M Overview General Considerations Common-Source Amplifiers Common-Drain (Source-Follower) Amplifiers Common-Gate Amplifiers Cascode Amplifiers DN, 2020 V.T.M Common Source (CS) Basics  In common-source amplifiers, the input is (somehow!) connected to G and the output is (somehow!) taken from D  We can divide CS amplifiers into two groups:  Without source degeneration (no body effect for the main transistor)  With source degeneration (with body effect for the main transistor) DN, 2020 V.T.M Common Source Basics  Different types of loads can be used in an amplifier    Resistive Load Diode-Connected Load Current-Source Load  The following parameters of amplifiers are very important   DN, 2020 Small-signal gain Voltage swing V.T.M Resistive Load 10  The region of operation of M1 depends on its size and the values of Vin and RD  We are interested in the small-signal gain and the headroom (which determines the maximum voltage swing)  We will calculate the gain using two different methods  Large-signal analysis  Small-signal model DN, 2020 V.T.M ...
