... When a negative voltage is applied across the collector-to-emitter terminal, the junction J1 becomes reverse-biased and its depletion layer extends into the N- drift region. The break down voltage during the reverse-blocking is determined by an open-base BJT formed by the P+ collector/ N- drift/P ba ...

Current source



A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
