Splet16. maj 2014 · To turn on our transistor switch all that is needed is to short resistor R1 to the negative ground. While PNP transistors are normally used for a negative ground configuration, it is possible to use a NPN transistor if a positive ground configuration is desired as indicated in Figure 2. SpletThe model we use for the sleep transistor depends on its region of operation, see Fig.2. When the sleep transistor is switching, it works in the saturation region. In the satura-tion stage, the sleep transistor can be modeled as a current source with a triangle waveform. The peak current is expressed by Sakurai’s alpha-power-law [8] formula: (1)
