%0 Journal Article %T Sinusoidal Frequency Doublers Circuit With Low Voltage + 1.5 Volt CMOS Inverter %A Bancha Burapattanasiri %J International Journal of Computer Science and Information Security %D 2009 %I LJS Publisher and IJCSIS Press %X This paper is present sinusoidal frequency doublers circuit with low voltage + 1.5 volt CMOS inverter. Main structure of circuit has three parts that is CMOS inverter circuit, differential amplifier circuit, and square root circuit. This circuit has designed to receive input voltage and give output voltage use few MOS transistor, easy to understand, non complex of circuit, high precision, low error and low power. The Simulation of circuit has MOS transistor functional in active and saturation period. PSpice programmed has used to confirmation of testing and simulation.Keywords-component; sinusoidal frequency doublers; low voltage; CMOS inverter; %K sinusoidal frequency doublers %K low voltage %K CMOS inverter %K IJCSIS %K Journal of Computer Science %U http://arxiv.org/pdf/1001.2264v1
