This circuit was found in an American documentation from 1970. We can increase the number of multiplier steps to have higher output voltage. The operating frequency is around 1.35 kHz.
This basic 100 kHz oscillator is suitable for use in calibration. We found it in documentation from the...
Found in a 1968 EEE, this circuit accepts frequencies from 1 to 1000 Hz and control voltages from 0.1 to...
National Semiconductor suggests the circuit shown in the figure for amplifying signals from two...
