What is stick diagram in CMOS?
stick diagrams are a means of capturing topography and layer information using simple diagrams. Stick diagrams convey layer information through colour codes (or monochrome encoding). Acts as an interface between symbolic circuit and the actual layout.
What is layout stick diagram?
Stick diagram is a draft of real layout, it serves as an abstract view between the schematic and layout. The gate and source of a depletion device can be connected by a method known as butting contact.
How can you realize AND and OR gate by CMOS NAND gate?
To build an inverter from NAND, simply connect the two inputs of the NAND together and use this junction as input of the inverter. Therefore an AND gate can be realized simply as a NAND followed by another NAND with 2 inputs tied together.
Which colour is used for implant?
Yellow color
Solution: Yellow color is used to represent implant layer.
What does the green color represent in the stick diagram?
Explanation: Green color is used to show the presence of n-diffusion layer. The n-type diffusion will dope the source or drain region in the p-well region. 3.
Which color is used for P diffusion in stick diagram?
Yellow/Brown
Stick Diagram Colour Code
| P diffusion | : | Yellow/Brown |
|---|---|---|
| N diffusion | : | Green |
| Polysilicon | : | Red |
| Contacts & Taps | : | Black |
How does a CMOS NAND gate work?
A NAND gate places two n-channel transistors in series to ground and two p-channel transistors in parallel connected to +V. Only when both inputs are logic 1, the output goes to logic 0.
What is CMOS made of?
CMOS (complementary metal-oxide semiconductor) is the semiconductor technology used in the transistors that are manufactured into most of today’s computer microchips. Semiconductors are made of silicon and germanium, materials which “sort of” conduct electricity, but not enthusiastically.
Why titanium is used in implants?
Titanium (Ti) and its alloys are widely used for medical and dental implant devices—artificial joints, bone fixators, spinal fixators, dental implant, etc. —because they show excellent corrosion resistance and good hard-tissue compatibility (bone formation and bone bonding ability).
Why does bone grow on titanium?
Its ability to physically bond with bone gives titanium an advantage over other materials that require the use of an adhesive to remain attached. Titanium implants last longer and much higher forces are required to break the bonds that join them to the body compared to their alternatives.
What is stick diagram color code?
Stick Diagram Colour Code
| Red | Polysilicon |
|---|---|
| Green | N diffusion |
| Yellow / Brown | P diffusion |
| Blue | M1 |
| Purple (Magenta) | M2 |
Which Colour is used for implant?
What does the Green color represent in the stick diagram?
How does a CMOS act as inverter?
You can easily see that the CMOS circuit functions as an inverter by noting that when VIN is five volts, VOUT is zero, and vice versa. Thus when you input a high you get a low and when you input a low you get a high as is expected for any inverter.
