I. Reading Exercises:
Exercise 1. Read and memorize using a dictionary:
promise, performance, cutoff frequencies , lithography, gate lengths, inherent, is allotted, degradation, adaptable radios, circuit blocks, on-chip circuits, off-chip narrowband RF circuits, adjacent bands, off-chip filters, passband, heterodyne radios, intrinsic dc offsets. |
Exercise 2. Answer the questions:
What promise do new process technologies show?
What is CMOS?
What is BICMOS?
How is a SiGe BICMOS process utilized?
Exercise 3. Match the left part with the right:
1. BICMOS offers performance that |
a) inexpensive lithography |
2. SiGe BICMOS can achieve these levels with |
b) a narrow band of frequencies in a very broad spectrum |
3. Each wireless standard is allotted |
c) matching to off-chip narrowboard RF circuits |
4. Multistandard radios will dynamically select on-chip circuit for |
d) can enable universal or multistandard analog radios |
Exercise 4. Open brackets choosing the right words:
In CMOS (apparatus/device) (velocities/speeds) are strongly determined by gate lenths which are now moving to (smaller/less) than 0.2 micron in order to (propose/offer) (velocity/speed) comparable to that of SiGe.
II. Speaking Exercises:
Exercise 1. Describe process technology; CMOS; BICMOS; IC; analog to digital converter using the suggested words and expressions as in example:
process technology is; the semiconductor manufacturing flow; which; creates or fabricates; an integrated circuit. example: Process technology is the semiconductor manufacturing flow which creates or fabricates an integrated circuit. |
CMOS Complementary Metal Oxide on Silicon; enables; low power; high-density chips. |
BICMOS Bipolar Complementary Metal Oxide on Silicon; an integrated circuit; fabrication technology; that; combines; the two major; IC technology; bipolar and CMOS; on one IC. |
IC (Integrated Circuit) a silicon chip; containing hundreds; thousands; or; millions; of; circuits elements; such as; transistors; resistors; capacitors; and inductors. |
analog –to- digital converter converter; that; changes; real-world analog; signals; such as; light; and; sound; into; digital code. |
Exercise 2. Ask questions to the given answers:
Question: _____________________________?
Answer: Radios that comply with many wireless standards may be required to support the complexities inherent in third-and fourth generation wireless systems.
2) Question: _____________________________?
Answer: Adaptable radios will use the high-speed transistors to switch the microwave signals associated with differing wireless standards through circuit blocks configured for these standards.
Question: _____________________________?
Answer: Independent of the radio standard being utilized radio must be capable of receiving signals as small as a few microvolts in the presence of unwanted signals in adjacent bands that may be more that 80-dB stronger
