DOI: 10.1109/access.2020.3041687
Abstract: This paper presents a four-phase passive mixer-first receiver using a common-gate (CG) trans-impedance amplifier (TIA), instead of a conventional shunt-feedback amplifier. The four-transistor TIA used in this work combines current-reuse with cross-coupled $g_{m}$ -boosting to… read more here.
