Circuits

Here is a collection of circuits that I built while learning about the behaviour of transistors. These are built primarily using the 2n3904 NPN bipolar junction transistor.

NOT Gate

NAND Gate

3-Input NAND Gate

NOR Gate

XOR Gate

Full Adder

Still to come:

• Clock (A-Stable Multivibrator)
• SR Latch
• D Latch
• D Flip-flop
• Edge Triggered D Flip-flop (Master/Slave)
• Edge Triggered D Flip-flop with 3-input NAND Gates
• Ring Counter (From D Flip-flops)
• Binary Counter (From D Flip-flops)
• Binary Counter (With enable, from JK Flip-flops)
• Adder
• Decoder
