Due to this change the operating point will shift. • For small-signal transistors (e.g., not power transistors) with relatively high values of β (i.e., between 100 and 200), this configuration will be prone to thermal runaway. umass sports medicineWebβ for any transistor is determined by its design: it cannot be altered after manufacture. It is rare to have two transistors of the same design exactly match because of the physical variables affecting β. If a circuit design relies on equal β ratios between multiple transistors, “matched sets” of transistors may be purchased at extra cost. thorium items
