This circuit was found in the November 1974 Radio Electronics magazine. The voltage depends on the supply and the timings of R1 and R2 as well as C1 and C2.
We found this oscillator in a 1978 amateur radio documentation. The circuit supports other...
Small time intervals up o some minutes can be achieved with this circuit. Only incandescent lamps...
In the figure we show yet another CMOS component based voltage controlled oscillator circuit. The...
