Abstract: The dielectric analyses are usually done using capacitance measurement technique. A set of sinusoidal wave frequency are applied to the capacitance. This paper is about the design of digital control frequency of sinusoidal wave generator that will be one of the main parts of dielectric analyzer. The ranges of the frequency are from 1 Hz until 100 kHz. This design is consist of three main parts. First is the triangle generation circuit. Second is the triangle to sine wave conversion circuit, and the third part is the amplification circuit. The output frequency of sinusoidal wave is depending on the input clock. Combination of up and down counter with digital to analog converter will produce the triangle wave. The triangle is then converted to sinusoidal wave. Two methods for triangle to sinusoidal wave conversion will be compared in this paper. The total harmonic distortion (THD) of both method output will be measure to make sure witch method is suitable in the design. Lastly, the output sinusoidal wave will be amplified through the amplification circuit. Simulation process will be done to demonstrate the design effectiveness.
