    Abstract

    A mixer-first receiver (MFRX) that breaks the baseband (BB) input linearity, matching, and noise trade-off is proposed. The MFRX is composed of a quadrature hybrid and two identical transimpedance (TIA) based MFRXs, with a noiseless antenna matching achieved by placing a termination at the hybrid’s isolated port. The receiver (RX) performance is analyzed utilizing a linear time-invariant (LTI) model and a comparison to previous approaches is presented. A TSMC 65nm CMOS design is presented as a proof of concept. Simulation results show superior performance over voltage-mode topologies of MFRXs in merits of in-band (IB) and out-of-band (OOB) linearity at the cost of power and area, with almost no noise penalty.
