We found this circuit in a 1965 Electronic Design. Transistors are still common but admit equivalents for some of them. The circuit drains a current of only 4 mA.
The different aspect of this source is the use of a 12 V lamp as a current regulator together with a...
This TTL oscillator can be used as clock in many applications. The output signal is square and the...
The voltage gain of this circuit is 1,000. This gain is given by the ratio between the 10 M ohm...
