CMOS on-chip active RF tracking filter for digital TV tuner ICs
A full frequency band active RF tracking filter design for a digital TV tuner is implemented for the first time. By combined control of the Gm and C values in the biquad of the Gm-C filter, the proposed tracking bandpass filter satisfies full frequency band tuning while maintaining narrow bandwidth. The Gm cell of the tracking filter is based on a dynamic source degenerated differential pair wi...
متن کاملA Tunable Wideband Rf Front-end for Sdr
Today’s direct-conversion SDR platforms are capable of tuning over extremely wide frequency ranges compared to traditional superheterodyne transceiver architectures. However, these radios can suffer from a number of problems due to a lack of front-end RF filtering, including poor dynamic range and desensitization. In this paper, we examine preliminary work on a tunable bandpass filter we are de...
متن کامل2.1 Mobile RF Front End Integration
The mobile phone has become a big part of our daily lives, which has created an exponential growth in network data and an ever-increasing complex RF Front End to support this growth. This in turn has demanded more complex requirements for the filters, switches and power amplifiers (PA) in the front end. In order to address this increase in complexity, there has been a migration from discrete so...
متن کاملGreen radio despite "Dirty RF" front-end
In this article, we show that the non-ideal Radio-Frequency (RF) front-ends have to be corrected in order to contribute in a Green radio development. In fact, the effects of typical RF imperfections, like nonlinearities, carrier frequency offsets, and IQ imbalances, can be compensated for, when digital correction algorithms are applied. Such algorithms enable Green applications (e.g., Orthogona...
متن کاملA Low Power and Low Noise On-Chip Active RF Tracking Filter for Digital TV Tuner ICs
In this paper, a highly linear and low noise CMOS active RF tracking filter for a digital TV tuner is presented. The Gm cell of the Gm − C filter is based on a dynamic source degenerated differential pair with an optimized transistor size ratio, thereby providing good linearity and high-frequency operation. The proposed RF tracking filter architecture includes two complementary parallel paths, ...
