Operating at just 1.35 V this circuit was found in a 1969 Electronic Design. The circuit makes use of transistors of the time but can be implemented with current equivalents.
This source can supply currents up to 1 A. The circuit is from Motorola's 1993 Linear Interface ICs....
The purpose of this receiver is to monitor the signal from a nearby transmitter. It was published in an...
In the figure we have a symmetrical power supply stabilized by a zener diode. Transformer and...
