Found in a 90's EDN, this circuit can be used as a shield. The components depend on the MOSFETs and the load that must be controlled. The logic is TTL.
This circuit produces the ticking of a clock on a common piezoelectric transducer. The circuit has an...
The basis of this circuit is a double T in the feedback, which has the components calculated to...
This configuration was found in the Texas Instruments optoelectronics manual. PNP transistors...
