Performance Improved Voltage Controlled Oscillator and Double Balanced Mixer Chip Design

This article presents a low-power and layout dimension efficient LC-VCO (voltage-controlled oscillators) and double balanced mixer are designed and implemented in tsmc
$0.18\mu\mathrm{m}$
COMS 1P6M process for microwave communications applications. The proposed VCO circuit applies PMOS cross-coupled pairs LC circuits. From the sourcing voltage of 0.9 V, the overall VCO total power dissipation of 1.54 mW, and tuning range is 532 MHz from 9.25 to 9.78 GHz. The double balanced mixer proposed converter gain of 8 dB, noise figure of 15.6 dB, IIP3 of −4.6 dBm, input P
1dB
of −1 6dBm. The tuning voltage is from 0 to 0.9V, and chipset core placement with layout optimization is 0.24mm
