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) SpletThis occurs when VC = 0, meaning that the transistor is a dead short to ground. In this state, the transistor is said to be in saturation mode. In this mode, the transistor collector current is the maximum that the circuit conditions allow, and increasing base current will not cause it to go any higher.
