What is the circuit diagram of NOR gate?
A NOR gate can be realized by using two bipolar junction transistors. The basic transistor circuit diagram is shown below. This circuit is made by two parallel-connected transistors. In the circuit when both A and B are given +5 V, base of the both transistors gets quite a high potential to make the transistors ‘ON’.
What is the stick diagram?
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 stick diagram and layout?
A stick diagram is a kind of diagram which is used to plan the layout of a transistor cell. The stick diagrams uses “sticks” or lines to represent the devices and conductors. Figure below shows the schematic of an inverter.
How many inputs can NOR gate have?
As with the OR function, the NOR function can also have any number of individual inputs and commercial available NOR Gate IC’s are available in standard 2, 3, or 4 input types. If additional inputs are required, then the standard NOR gates can be cascaded together to provide more inputs for example.
What does stick diagram reflects?
Stick diagram gives the position of placement of the element. Explanation: Stick diagram does not show exact placement of components, transistor length, wire length and width, tub boundaries, etc.
What are layout diagrams?
As you develop a model diagram and add more elements and connectors to it, you can apply one of a number of formats to automatically lay out specific areas or sets of elements in the diagram in a structured arrangement.
What is stick diagram & mask layout?
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.
Does gate have 4 inputs?
Because the Boolean expression for the logic AND function is defined as (.), which is a binary operation, AND gates can be cascaded together to form any number of individual inputs. However, commercial available AND gate IC’s are only available in standard 2, 3, or 4-input packages.
Is gate input or 4?
Like the AND gate, the OR function can have any number of individual inputs. However, commercial available OR gates are available in 2, 3, or 4 inputs types. Additional inputs will require gates to be cascaded together for example.
