WebIn this collector-to-base bias setting, two resistors supply the transistor’s active region with DC bias despite β’s value. Since the DC bias comes from the collector voltage (V C), it ensures excellent stability. Rather than the supply voltage rail (V CC), the base bias resistor (R B) connects to the transistor’s collector (C). An ... Web2 shows Shapiro steps begin at approximately 1.5 mA of applied DC bias to the FJTL for all frequencies applied. When globally biased at a current of about 3.5 mA, for example, the FJTL can source or sink up to about 1.5 mA of current and remain operational. The voltage developed across the FJTL is extremely stable for a large range of global ...
