Problem:The improvement in the performance of VCO can be achieved by increasing the quality factor of the resonant tank circuit. Especially, the inductor quality factor affects the quality factor of the circuit and phase noise of the VCO.  Approach: This paper presents a compact coupled pyramid inductor for the design of VCO, amplifier, and filter applications. The inductor is designed using Sonnet software in a pyramid and coupled pyramid structure to reduce the capacitive parasitics and losses. Furthermore, the inductance and quality factor of the coupled inductor is enhanced by tapering the width of the conductor and stacking the metal layers to reduce substrate losses and eddy current losses. Findings:The effect of quality factor and inductance are validated by designing a VCO at 3.15 GHz. The simulated best phase noise for the VCO is -125 dBc/Hz @ 1MHz, and the figure of merit is -216 dBc/Hz at 1 MHz offset. Conclusion: The proposed coupled pyramid inductor achieves better output power, tuning range, and figure of merit, which makes it a good candidate for applications in the design of filters, amplifiers, oscillators, and receiver circuits for various wireless communication systems and telemetry transponders.
