A low-IF very compact low power quadrature receiver for ZigBee applications is presented. The receiver saves area and power with a quadrature self oscillating mixer based on high Q bond-wire inductors. The prototype, integrated in CMOS 90nm, provides 76dB of maximum voltage gain, with a 10dB noise figure, an IIP3 of -13dBm and a phase noise of 124dBc/Hz LO @ 3.5MHz with an active area of only 0.23mm2 and a power consumption of 3.6mW (including the baseband filter).

Abstract
A low-IF very compact low power quadrature receiver for ZigBee applications is presented. The receiver saves area and power with a quadrature self oscillating mixer based on high Q bond-wire inductors. The prototype, integrated in CMOS 90nm, provides 76dB of maximum voltage gain, with a 10dB noise figure, an IIP3 of -13dBm and a phase noise of 124dBc/Hz LO @ 3.5MHz with an active area of only 0.23mm2 and a power consumption of 3.6mW (including the baseband filter).File in questo prodotto:
