摘要：The operation of a bipolar transistor is controlled comprising by producing afirst voltage that is a product of a static collector current of the bipolar transistor timesan emitter resistance. The first voltage is then compared to a predetermined reference
voltage to produce a control signal. Current is then injected a base of the bipolar
transistor in response to the control signal. In a specific implementation, the first voltage,which is a product of the static collector current (Ic) of the bipolar transistor times itsemitter resistance (RE) , is slaved to a predetermined reference voltage (Vref) whosevalue is substantially equal, to within a tolerance, to 13 mV at a temperature at or about27° C.
