The Si Darlington transistor pair of the figure shown has negligible leakage current. As R2 approaches infinity, find the value of R1 needed to bias the circuit so that VCEQ=6V. Using KVL and Ohm’s ...
The circuit in Figure 1 sinks a constant current (ICE3) through Q3’s collector and emitter. This design is balanced so changes in Q3’s base-emitter voltage (VBE) don’t affect the current sink’s ...
