① Explain how to design logic gates with transistors.
- All of the gate is made by basic gates(AND, OR, NAND, NOR, NOT).
So I explain the basic 5 gates.
1) AND gate
When all input is 1, output of AND gate is 1.
Transistor has 3 input, those are Base, Collector, Emitter.
Among these, Base and Collector is input node, Emittor is output node.
So the circuit is as follows. as Y=AB
When both of Input A and B are 1, both transistor pass current and output is 1. However, if one of transistor was 0, output is 0.
2) OR gate
When at least one input is 1, output of OR gate is 1.
Likewise, Base and Collector is input node, Emittor is output node.
So the circuit is as follows. as Y=A+B
Because both of transistors connected to output, If one of transistor was 1, output is 1. However, if both of transistors are off, output is 0.
