摘要：
An ultralow power (ULP) low-noise receiver front-end for the BLE application is presented in this letter. The tradeoff between noise and power consumption is mitigated by employing a transformer-based passive gm-boosting common-gate low noise transconductance amplifier (LNTA). Local-positive feedback (LPF) and feedforward (FF) noise cancellation techniques are combined in the LNTA to further lower noise. After the passive mixer, a TIA implements complex filtering with a moderate conversion gain. The receiver front-end, fabricated in TSMC 28-nm process, consumes only 440 mu Wunder 0.9-V supply with a minimum noise figure of 4.8 dB.
