    Abstract

    A low-noise, low-power and wideband RF-to-baseband (BB)-current-reuse quadrature (I/Q) receiver front-end using an active-inductor (AI) technique is proposed to support several local and wide-area wireless standards from0.8 GHzto3.4 GHz. To achieve low-power, a single supply and DC bias current are shared between a low-noise transconductance amplifier (LNTA) and a transimpedance amplifier (TIA). A double-balanced current driven passive mixer with a 25% duty-cycle local oscillator (LO) to enhance the overall performance are used. To improve the gain and noise performance of the receiver,a high impedance AI is employed to isolate the RF signal path from the output node and BB signal that allows the receiver to operate at higher frequencies with minimum degradation.Agm-boosted capacitive cross-coupled common-gate (CCC-CG)LNTA topology is employed to enhance input-matching, gain and NF without consuming extra power.
