ABSTRACT:
A DC voltage control device comprising first and second R-S flip-flops, two diodes and an analog memory comprising a MOS field-effect transistor, a nonpolarized capacitor and an analog switch. The DC voltage may be increased, decreased and maintained at a desired level. Because of the analog memory, the signal level is stored or maintained even in case of power failure. The DC voltage control device may be used as a brightness control of an incandescent lamp, VCF (voltage controlled frequency) of a sweep generator and so on.
