Magnetic frequency multipliers
Electrical Engineering, 1954WITH the availability of high-quality magnetic core materials, it has become possible to develop very efficient magnetic frequency multipliers. The advance of the electronic arts in the development of computers and precise control systems has created the immediate need for frequency multipliers which can produce exact multiplication of frequencies in ...

Frequency multiplier with a feedback
Measurement Techniques, 1964A multiplier with a feedback has the unique combination of the following properties: a wide range of multiplied frequencies (10:1 and wider); a large and easily variable scaling factor; it is independent of the input signal voltage shape or amplitude; it can operate with a variable input frequency; it is insensitive to stray frequency modulation of the

A Low-Power Clock Frequency Multiplier
2006 IEEE International Symposium on Circuits and Systems, 2006A low-power output feedback controlled frequency multiplier is proposed for delay locked loop (DLL) based clock synthesizers. It uses N voltage controlled delay lines (VCDL) to multiply the input clock frequency by a factor of N/2. This frequency multiplier is less susceptible to jitter-accumulation.

A frequency multiplier for reference frequency in frequency synthesizer systems
Analog Integrated Circuits and Signal Processing, 2017A low jitter frequency multiplier, which requires less power, area, and design complexity than reference multiplying PLL or DLL circuits can be used to generate the reference frequency for a low phase noise frequency synthesizer. This paper proposes a mixed signal solution based on the fact that the average DC value of a signal is proportional to its ...

1984
At frequencies up to the order of 120-150 MHz, it is possible to use a quartz crystal as resonator and thus achieve simultaneously a high Q and good frequency stability and accuracy. At still higher frequencies the phase noise performance of a simple oscillator will be degraded both due to the higher value of f0 and simultaneously the lower Q of a ...

A New Electronic Multiplier for Power Frequencies
Transactions of the American Institute of Electrical Engineers, 1940THERE are many electrical applications which require alternating current at higher frequencies than those normally obtained from the power lines. These applications include: induction heating, the operation of high-speed motors, and the operation of fog horns and underwater signaling devices.
