We show in the figure how to implement the No-AND or NAND logic function using a general-purpose transistor. The 47 k base resistors and collector can be changed to other supply voltages.
The frequency of this oscillator depends on the crystal used and the transistors. The circuit was...
This circuit shows how to use the 4007 MOSFETs in an amplifier stage. We found it in an...
This circuit was found in a 1967 Japanese documentation. It consists of a touch control system with...
