The insulation formed on top of a slab of silicon substrate

The insulation formed on top of a slab of silicon substrate is silicon phosphorus. boron silicon. silicon dioxide. boron phosphorus. What is the pulse width (duration) of a 500-Hz digital signal if the duty cycle is 20%? 0.2 msec 1.0 msec 0.4 msec 2.0 msec The highest value you can read on a 3 1/2-digit DMM is 9.99 19.500 9.995 19.99 Increasing the value of resistors that are part of a logic device helps qualify the device for what family classification? Low-power TTL High-threshold DTL High-threshold TTL High-threshold RTL Another name for a MODULO 10 counter is a base 10 adder. decade counter. decade decoder. 1-of-10 decoder. In this diagram of a CMOS transistor pair, the N + and P+ cells are created by dielectric leakage. sputtering. diffusion. epitaxial growth. At what triggering source should you set an oscilloscope before you first turn it on? Automatic External Channel A internal Channel B internal

Solution

1)we use silicon dioxide for insulating because silicon dioxide is excellent insulating and dielectric material.

2)pulse width duration = time period * duty cycle

time period = 1/frequency =1/500 = 2 ms

pulse width = 0.2*2=0.4 ms

3)3 1/2 dmm means the MCB can only read 1 or 0 where remaining can read from 0 to 9 , so the highest value will be 19.99

5) modulo 10 counter is also called as decade counter. Decade means 10

6) both N+ and P+ layers are formed using diffusion technique
