An ultra‐low‐power (ULP) CMOS full‐band (780/868/915/2400 MHz) ZigBee receiver front‐end is presented. The front‐end consists of a wideband common‐gate LNA and an I / Q current‐commutating mixer. Current reuse and active trans‐conductance ( g m ) boosting techniques are utilised in this design. Details on design and optimisation method for the proposed ULP receiver front‐end are provided. Measurement results for 180 nm RF CMOS implementation show the front‐end has a conversion gain of 25.2 dB at sub‐GHz bands and 17.5 dB at 2.4 GHz band. The minimum noise figure at sub‐GHz bands is 7.3 dB. The receiver front‐end consumes only 0.826 mA from a 1.0 V DC supply and the size of the core circuit is 0.052 mm 2 .
