- best toys to play with
for you to play.
we will have
entertainment, story, strategy and to have your virtual play mate
will be your playmate as her parents are different to the normal toys you play with. they have little differences to you and your play mates. her parents love their daughter and her playmate, they are just different.
don't let her know anything about the difference, but be as friendly as you can be.It is well known that a process or a circuit is more susceptible to noise, and particularly to noise generated by other circuits and by the environment in which it is used, when it has a greater supply voltage and thus less internal resistance. This is why it is conventional practice to reduce the supply voltage of a circuit, for example to 1.2 volts in order to increase its immunity to noise.
This solution is satisfactory for a very large number of circuits, such as logic circuits, but this approach is not appropriate for other types of circuits, in particular analog circuits. Thus, it is not suitable to reduce the supply voltage of a circuit, for example to a level of 0.5 volts, since this results in a significant reduction in the performance of the circuit.
There are analog circuits, in particular non-linear, which require a supply voltage of the order of 1 volt.
The circuits of this type are used in particular in radiofrequency applications, especially in mobile telephone applications, and in particular in mobile telephones operating under the GSM standard.
FIG. 1 shows a conventional circuit diagram of a differential amplifier circuit 10, which is also known as a transconductance amplifier circuit. The differential amplifier circuit 10 is designed in CMOS technology and includes two transistors T1 and T2 connected in series between a supply line and a ground line. The first transistor T1 is connected to a high reference voltage source VDD and the second transistor T2 is connected to a low reference voltage source, for example to a ground. The differential amplifier circuit 10 receives as its input signals IN and INB an input voltage VIN and an input voltage VINB in the “b” (“−”) or “−” direction (the case in which the input voltage VIN is greater than the input voltage VINB).
The circuit 10 includes a circuit known as the “common-source amplifier”. It is known that it is difficult to ensure the stability of the amplifier
