A Current-Tripler dc/dc Converter
IEEE Transactions on Power Electronics, 2004This paper proposes a novel zero-voltage-switching (ZVS) current-tripler dc/dc converter. Compared to the conventional phase-shifted ZVS full-bridge dc/dc converter with current-doubler rectifier, the proposed current-tripler dc/dc converter reduces the synchronous rectifier (SR) conduction loss as well as the transformer winding loss. Furthermore, the

Unstable oscillations of magnetic triplers
IEEE Transactions on Magnetics, 1968Static magnetic frequency multipliers are often unstable because of various resonance conditions that can arise when capacitors are associated with nonlinear magnetic devices. Such resonance conditions can occur at many different harmonic or other frequencies and are influenced by many factors.

Design of a 114GHz-135GHz passive tripler
2010 International Symposium on Signals, Systems and Electronics, 2010We report on the design, fabrication and testing of a 114GHz to 135GHz passive tripler. No mechanical tuners and the simple circuit topology make it easy and cheap to fabricate the tripler. The circuit design, simulation and optimization of the tripler are carried out by using HFSS and ADS.

Design of millimeter-wave CMOS frequency tripler
2011 International SoC Design Conference, 2011The design of millimeter-wave frequency triplers using sub-harmonic mixing and injection-locking is discussed. The design goals are aimed at low power consumption, high harmonic rejection, and bandwidth extension. Several circuit design techniques will be reviewed for consideration of these goals.

Crucial problems in the design of a terahertz tripler
Journal of Semiconductors, 2015A frequency-multiplied source at the terahertz band using discrete planar Schottky diodes, which is a critical element in heterodyne instruments, has been studied by some domestic research institutions in recent years. Besides the design method, there are still many crucial problems that must be taken into consideration in the design.

A microstrip tripler to 47 GHz
1987 Twelth International Conference on Infrared and Millimeter Waves, 1987This paper describes a planar microstrip millimeter-wave tripler to 47 GHz fabricated on an alumina substrate and using a commercially available varactor diode. Unlike waveguide multipliers the microstrip tripler can be directly-integrated with an FET DRO. The tripler provides +12 dBm output power which is ample to drive a typical millimeter-wave mixer.

Unbalanced operation of a magnetic frequency tripler
IEEE Transactions on Magnetics, 1982This paper considers a magnetic frequency tripler operating from an unbalanced three-phase supply. It is shown that even small unbalances can significantly alter the normal behaviour of the device and lead to undesired operating modes. This paper outlines a method of analysis and offers general guidelines for the design of stable devices.

Low-Voltage Analog Tripler Circuit
Analog Integrated Circuits and Signal Processing, 2001A new low-voltage CMOS tripler is presented in this paper. It is realized by the square-law characteristics of MOS transistors operating in saturation. The proposed circuit has been fabricated in a 0.8 μm CMOS process. Experimental results have been given to demonstrate the feasibility of the proposed circuit. It is expected to be useful in low-voltage
