【 摘 要 】

This paper presents a low phase noise multi-band LC VCO using a switched differential inductor in a standard 0.18 µm CMOS technology. In the proposed LC VCO, it is achieved multi-bands of 0.9, 1.8, 2.4, and 4.5 GHz, and the phase noises of −133, −135, −125, and −127 dBc/Hz at 1 MHz offset, respectively. The chip size is 1.0 × 1.1 mm2 including pads. The DC power consumption is 16.2 mW at 1.8 V supply voltage.
