a)Describe in an essay no longer than 400 words your own understanding of a validity of Moore's Law for the digital CMOS transistor scaling. Address the following issues:the dimensions of

transistors, the density of transistors, the operational frequency of transistors, the design of digital circuits made of the transistors, the number of cores in a processor, and the cost of the transistors related to the cost of fabrication and to the cost of a technology development. b)Find at least four technology innovations which had to be introduced into the technology nodes to boost a performance of CMOS transistors in order to meet requirements for digital circuits and thus continue the scaling. Write a maximum of 300words essay to explain the technical reasons for your selected technology innovation.Justify that your technology chosen change is an innovation.18 marksl c)MOSFET which has a conduction parameter of 50 mAN? and a threshold voltage of0.5 V. If the supply voltage is +15 Vand the load resistor is 365 Q, calculate the values of the resistors required to bias the MOSFET amplifier at 1/3 (VDD).A common source MOSFET amplifier is to be constructed using an n-channel d)How is a gain (A) in a MOSFET based amplifier related to the input resistance (RIN)and the output resistance (RouT) ?1 morl1
