Low power consumption voltage controlled oscillator design

Voltage Controlled Oscillators (VCOs) are extremely important components in the exploding field of wireless radio-frequency communications. This paper illustrates the design and fabrication of a unique compact and low power consumption VCO for wireless communication. Subsequent to a description of the design technique, the paper discusses the measured results of a VCO, realized with the design procedure, which was fabricated using lumped components on microstrip dielectric substrate having a dielectric constant of 2.17 and a thickness of 20 mils. Excellent circuit performance is shown to result for very low bias power (1 V, 0.86 mA) values.
