Access to the web portal Username. For a current source load CS amplifier: Here in order to make the load work as a current source at all time it must be in saturation region. Some of your explanations seem to be trying to understand the amplification by thinking of how the operating points of the PMOS and NMOS will change for the same input signal. The model is essentially the same as that used for the JFET. This is accomplished by taking energy from a power supply and controlling the output to duplicate the shape of the input signal but with a larger (voltage or current) amplitude. Both current and voltage gain can be described as medium, but the output is the inverse of the input, i. Operation of cmos common source amplifier output The current- source load can be implemented using a PMOS transistor and is therefore called an active load, and the WebMail Studenti.

(LogOut/ Transimpedance Amplifier The signal current at the input flows into the summing node of a high-gain amplifier. This type of amplifier is called as common gate amplifier. It is also possible to apply the input signal to the source terminal by keeping common gate terminal. Think of what would happen if you had two separate voltage sources on the two transistors' gates and you increased only the one connected to M1: ID1 would increase and drain more charge from Vout (where there will always be some capacitance) than that ID2 (which hasn't changed) is adding on the same node, hence discharging it and reducing Vout. The important point is the gain is positive, further the input impedance is given by which shows that the input impedance of common gate amplifier is relatively low. The only difference is their resistances are nonlinear and vigorously change when the input voltage slightly varies; so, this is an extremely sensitive "electronic potentiometer". Now well determine the small-signal voltage gain and output resistance of this amplifier. As can be seen the different configurations or topologies have different characteristics. Furthermore, it is useful to observe the graphical construction of the transfer function vO/vI for this amplifier, as illustrated in Figs.
