A Low Power Quadrature Voltage Controlled Oscillator Design for 2.4GHz ISM Band Application
Abstract— A low power Quadrature voltage controlled oscillator (QVCO) design for 2.4GHz ISM band,
fabricated by using CMOS 0.18um process, is presented in this paper. The tuning range of the proposed
QVCO is mainly broadened by a novel negative resistance, variable capacitance and tapping inductance
design. Simulation results of the proposed QVCO reveal phase noise of -111@1MHz and tuning range of
2.02GHz~2.549GHz (23.1%) while consumption is 4.93mW under the supply voltage ( dd V ) of 1.2V and
control voltage ( ctrl V ) of 0.7~1.8V. The core area of the designed chip is 1.2mm*1.2mm.
Index Terms— QVCO, 0.18um, negative resistance, variable capacitance, tapping inductance, CMOS.
