A 1V 830μW full-band ZigBee receiver front-end with current-reuse and Gm-boosting techniques
A low-voltage low-power CMOS ZigBee receiver front-end supporting 780/868/915/2400MHz bands is presented in this paper. The wideband common-gate (CG) low noise amplifier (LNA) and the I/Q current-commutating mixer are merged in a single circuit, sharing the bias current. Active trans-conductance (gm) boosting technique is utilized in the design of the presented receiver front-end. The topology and optimization method of the presented front-end are shown. Post-layout simulation results for 180nm RF CMOS implementations show the conversion gain is 26.5dB at 780/868/915MHz bands and 19.5dB at 2400MHz band. The minimum simulated NF is 6.5dB. The receiver front-end consumes 830μW from a 1V DC supply and the active size of core circuit is 0.0276mm2.
