RE: [TCML] Transistor Questions (slightly O.T.)
I've received the responses, though I'm still at a loss - what I'm asking is this:
Has there been a device manufactured, which behaves like a diode with zero base voltage, but when base voltage (negative or positive, base-to-emitter/collector is irrelevant for sake of questioning) is applied, the device turns 'off' and restricts current-flow. The closest analogy I can think of is a transistor which turns off in the presence of a base-current but, when there is zero base-current, is always on.
Here's an ASCII mock-up of the operation, as it would be seen on an O-scope:
Base Input:
10V ______ ______ ______ _______ ______
| | | | | | | | | |
| | | | | | | | | |
0V _ |_ _ _ | _ _ _ _ |_ _ _ | _ _ _ _ |_ _ _ | _ _ _ _ |_ _ _ | _ _ _ _ |_ _ _ |
_________________________________________________________________________________________________________________
Transistor Output:
10V ___ _________ _________ _________ _________ ______
| | | | | | | | | |
| | | | | | | | | |
0V _ |_ _ _ | _ _ _ _ |_ _ _ | _ _ _ _ |_ _ _ | _ _ _ _ |_ _ _ | _ _ _ _ |_ _ _ |
Thanks everyone,
