Question

1. Determine whether each sentence is True (T) or False (F)

a. Very fine surface patterns of various IC components can not be reliably reproduced using photolithography

b. Adding a source resistor to a CS (Common Source) stage will increase its DC bias stability, input resistance, and output resistance but have little effect on its voltage gain.

c. Intrinsic voltage gain of a CE amp is equal to the (Early Voltage/Thermal voltage) and independent of current collector.

d. Adding transistors or resistors to the simple current mirror can increase its output resistance but will reduce the output voltage swing possible.

e. Stacking a CG (Common Gate) or CB (Common Base) on top of a CS (Common Source) or CE (Common Emitter), respectively, will have little effect on the overall output resistance.

2. A key step in the design of MOS transistor amplifiers is to the transistor appropriately. Describe three indicators or hallmarks of a well biased MOS transistor.
