Abstract
An integrated low-power CMOS VCO and its divide-by-2 dividers for WLAN transceivers are presented.The VCO is based on on-chip symmetrical spiral inductor and differential diode and the divide-by-2 dividers are based on the ILFD technique.Due to differential LC tanks and ILFD techniques,power consumption is low.The circuit is implemented in a 0.18μm CMOS process.Measurements show the proposed circuit could produce 3.6/1.8GHz dual band LO signals with a wide tuning range and low phase noise.1.8GHz LO signals are quadrature.It consumes 5mA at VDD=1.5V.The size of die area is only 1.0mm×1.0mm.关键词
