Test: BiCMOS Technology - Electrical Engineering (EE) MCQ

One of the disadvantage of MOS technology is it has limited load driving capabilities.

MOS devices have limited current sourcing and current sinking abilities.

BiCMOS provides higher gain, better noise and high frequency characteristics than MOS transistors.

Some of the features of BiCMOS are low input impedance, low packing density, unidirectional, high output drive current etc.

 BiCMOS has high power dissipation and CMOS has low power dissipation.

BiCMOS is unidirectional and CMOS is bidirectional.

The quality of bipolar transistor can be improved by reducing the collector resistance, which can be done by using the additional layer of n+ subcollector.

 BiCMOS is more advantageous and improved than CMOS and it can be used in I/O and driver circuits.

The advantages of E-beam masks are it has tighter layer to layer registration and it has smaller feature sizes.

The two approaches to the design of E-beam machines are raster scanning and vector scanning.
