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.
This circuit was found in the June 1991 issue of Radio Electronics magazine. The circuit uses two...
The MOSFETs are of the type of power and the resistors have their values between 1 k and 10 k for...
In the figure we have the way to use an LED to increase the voltage of a zener. The increase...
