Which effect is the bottleneck of speed in microelectronic systems?
Which of the following can be used to represent the input of a transconductance amplifier?
What is a Microprocessor?
A D.C. voltage of 850mV is given to the base of a npn transistor, the reverse saturation current 5*10-17A while the emitter is grounded. The collector is attached to a 1KΩ resistor which connects to a 10V power supply. If VCE(sat) is 200mV, choose the maximum VBE to drive the device into saturation at room temperature.
