E6A10
In Figure E6-1, which is the schematic symbol for an N-channel dual-gate MOSFET?
Pick an answer to check it.
Answer: B. 4
Symbol 4 has two gates (G1 and G2) and an arrow pointing inward toward the channel, which marks N-channel. Symbol 5 is also dual-gate but its arrow points out, so it is P-channel.
Tip: Two gates, arrow in = N-channel dual-gate MOSFET.
