Abstract

A low power 5 GHz LC quadrature phase VCO with active inductor is designed and fabricated in standard 0.18 μm single-poly, six metal layer mixed-signal CMOS process. Active inductors are used in the design to diminish chip area consumption. Results based on post layout simulations are presented. Circuits are currently being fabricated through the MOSIS Educational Program. The core VCO dissipates 6.86 mW on a 1.8 V power supply. The whole circuit has an output power of -2.956 dBm. Simulated phase noise is shown as -74.6 dB/Hz at 1MHz offset and -102.3 dB/Hz at 10 MHz offset.
