A 12-mW Fully Integrated Low-IF dual-band GPS Receiver on 0.13-μm CMOS

Abstract: This paper presents the design of a dual-band L1/L2 Global Positioning System (GPS) receiver. A low-IF architecture was used for dual-band operation with analog onchip image rejection. The receiver is composed of dual-band LNAs and down-conversion mixers, a complex variable-gain channel select filter, analog AGC loop, and a 2-bit analog-todigital converter. The receiver is to be integrated with a phaselocked-loop synthesizer designed in another work [1]. The digital tracking correlator of the receiver is desig… Show more

“…The gain mismatch is measured to be 0.25 dB. Table 1 lists comparisons of the proposed LNA and the recently reported CMOS balun LNAs [1][2][3][4]. It can be seen that the proposed balun LNA achieves lower noise figure and higher voltage gain with lower power dissipation, compared with prior techniques listed.…”

“…Note that M 2 is the common-gate stage of the cascode configuration, used to eliminate the Miller effect and provides a better isolation from the output return signal. As can be seen, the proposed structure realises single-end to differential transition in the second stage and reuses the current of the first stage, which are the main differences between this structure and those of [1][2][3][4]. The large inductor L 1 is used to provide a high impedance path to block the RF signal from the drain of M 2 to the source of M 4 , and to provide a low impedance path to let DC current flow from M 4 to M 2 .…”
