“…A clearly defined impedance for wideband matching at the RF input port may be readily achieved by setting the transconductance of M1 to 50Ω. The CG stage has greater linearity than the CS stage [21]. The PMOS M3 and M4 transistors configured as load enable the maximum gain and minimize the NF.…”

“…Indeed, to attain the best performance, a suitable scaling of the CS stage is required not only for a low NF but also for low distortion. The nonlinearity of transconductance 𝑔 𝑚2 and output conductance 𝑔 𝑑𝑠2 is the principal cause of this distortion in addition to the dependence of 𝑔 𝑚2 on the drain source bias voltage [21]. Moreover, the best LNA linearity performance is obtained if the CS stage has a good linearity.…”

A double balanced passive mixer-based receiver operating in the 3-5 GHz UWB for medical applications is described in this paper. 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.
