This amplifier is from Motorola's 1990 Linear Databook. The circuit can be used with operating amplifiers with the same characteristics and the power supply must be symmetrical.
This circuit converts voltages from 5 to 12 V at voltages of 100 to 400 V. The transformer has a...
We found this CMOS circuit based on the PLL4046 in the December 1989 issue of Radio Electronics magazine....
We found this circuit in an old publication. The circuit can be implemented with modern equivalent...
