Which are the major key components are utilized by 8038 function generator according to monolithic technology?

a. Schottky-barrier Diodes
b. Thin-film Resistors
c. Both a & b
d. None

Correct Answer : c. Both a & b

Explanation :

Monolithic components like Schottky-barrier diodes & thin-film resistors forms the basis for 8038 function generator. The main characteristic of Schottky diode is that it can perform the rectification for signal frequencies exceeding 300MHz. Besides this, thin film resistors are mainly built -up by using Silicon or alumina.
A very thin layer is deposited over the substrate of thin film resistor comprising two layers of conductivity and resistivity. However, though they are expensive but provides better electrical properties as compared to thick or any other kinds of resistors in the monolithic package.
