#91391 - Could it be smaller? Responding to: ???'s previous message |
Michael Karas said:
Sometimes there is a tendancy for engineers to try to avoid circuits because they "have too many transistors". Is this a throw-back to the days when minimising the number valves (tubes) was a very important design goal...? BTW....Zetex makes a rather nice selection of dual bipolar transistor and mosfet devices Do they also do ones with built-in resistors? Now that'd make it really tiny...! |
