The circuit was designed to produce a frequency multiplier for low frequency from the measurement of their signals while eliminating the noise that comes with them. CA3130 – a BiMOS operational ...

This report discusses the design of circuits using variable-capacitance diodes as high efficiency frequency multipliers with particular reference to their use at v.h.f. and u.h.f. Two multipliers are ...

Crystals usually operate at fundamental frequencies up to about 15 MHz. Whenever higher frequencies are required a frequency multiplier is placed after the crystal oscillator. The resulting output ...
