Abstract : The recent availability of many different types of silicon capacitors or varactors has stimulated investigation as to applications. One outcome has been the design of parametric frequency multipliers with excellent conversion efficiencies. This report discusses the present theory and analysis of these devices by taking the results of Leeson and Weinreb and expanding them into more convenient design equations. The physical properties of the silicon capacitors are discussed and several graphs are provided to aid selection of units for a specific design. The body of the report details basic principles and design considerations, presents a compact design approach and gives a specific example for a cascade X18 multiplier unit. Limitations as to the present theory and practical results are discussed. The equations used to advance the design approach are derived. (Author)
