In the deep-submicrometer design regime, RF circuits are expected to be increasingly susceptible to process variations, and thereby suffer from significant loss of parametric yield. To address this problem, a postmanufacture self-tuning technique that aims to compensate for multiparameter variations is presented. The proposed method incorporates a ??response feature?? detector and ??hardware tuning...
This paper presents a two-stage wideband low noise amplifier (LNA) with active balun. The first stage adopts current bleeding and dc coupled common-drain feedback techniques to achieve high gain low noise figure and acceptable input matching over a wide frequency band. A conventional single-ended to differential convertor is used as a second stage. The proposed wideband LNA is designed for DVB-T application...
A post-linearization technique for the differential CMOS LNA is presented. The proposed method uses an additional cross-coupled FET pair which generates the 3rd-order inter-modulation (IM3) current to cancel out the IM3 current of the differential amplifier while minimizing the degradation of noise figure and avoiding the gain reduction. This technique is applied to enhance the linearity of the differential...
A novel linearization method is proposed for CMOS LNA design. The proposed LNA adopts two cascode FETs, one of which operates as a conventional current buffer delivering the fundamental current to the load and the other one works as a nonlinear current sinker absorbing the 3rd-order intermodulation distortion (IMD3) current generated by the common source FET. Both single-ended and differential structures...
