The receiver front-end circuit is composed of an inductorless low noise amplifier (LNA) followed by a fully differential voltage-driven double-balanced passive mixer. A duty cycle of 25% was chosen to eliminate overlap between LO signals, thereby improving receiver linearity. The LNA realizes a gain of 25.3 dB and a noise figure of 2.9 dB. The proposed receiver achieves an IIP3 of 3.14 dBm, an IIP2 of 17.5 dBm and an input return loss (S11) below -12.5dB. Designed in 0.18μm CMOS technology, the proposed mixer consumes 0.72pW from a 1.8V power supply. The designed receiver demonstrated a good ports isolation performance with LO_IF isolation of 60dB and RF_IF isolation of 78dB.}, type={Article}, title={Passive Mixer-based UWB Receiver with Low Loss, High Linearity and Noise-cancelling for Medical Applications}, URL={http://journals.pan.pl/Content/126540/PDF/9.pdf}, doi={10.24425/ijet.2023.144332}, keywords={WBAN, UWB receiver, LNA, passive mixer, linearity, ports isolation}, }
