A fully integrated low‐power 2.4 GHz ZigBee transceiver with inductor‐less radio‐frequency front‐end in 180 nm complementary metal–oxide–semiconductor is presented. The proposed double push–pull low noise amplifier collaborates with a current‐mode down‐converter to provide wideband low‐noise amplification, as well as the out‐of‐band blocker resilience. To save power, a sliding frequency synthesiser (FS) with a low‐frequency running voltage controlled oscillator is employed to provide the local oscillation for both the receiver and transmitter. Measurement results show that the RX reaches −102 dBm sensitivity and dissipates 11 mA power. The FS achieves −91 dBc/Hz in‐band phase noise with only 6.5 mA DC power. The TX features +7.6 dBm maximum output channel power, 4% error vector magnitude at the cost of 19.5 mA power.
