This circuit was found in Siliconix documentation from the 1980s. Equivalent operational amplifiers can be used and the output current is very low.
In the figure we show how a 2-pole x 2-position switch or HH should be connected to reverse the...
This circuit trips when the input signal goes through zero, triggering a direct current load. The...
Found in Philips' 1968 documentation, this circuit serves as a 6.3 V reference for high stability. |...
