In this paper, a low-power transformer-based Ku-band receiver front-end is implemented in a 180-nm CMOS technology. The transformer-feedback gain-boosting technique and forward-body-bias technique are employed in three-stage (common gate + 2-stage common source) LNA to achieve a low-power design. A resistive ring mixer is chosen due to its advantage of zero-dc-power. The receiver demonstrates a 4...
The paper aims at the RF front-end that has a single-output four-input structure. To realize four-antenna transmitting and four-antenna receiving functions, a single pole four throw (SPFT) switch and a power divider are used. The simulation results obtained by Advanced Design System (ADS), such as gain, spectrum and output power of the transceiver, indicating that the proposed strategy is feasible...
A blocker rejection receiver front-end for 840–960 MHz single-chip UHF RFID Reader is presented in this paper. The proposed receiver front-end injects the blocker replica signal into the differential LNA of RF front-end, through a feedback path to actively create a narrowband notch filtration for the self-jammer and not affect the gain for the backscattered tag signal. In contrast to the traditional...
The fast Fourier transform (FFT) is usually used to analyze the spectrum of electromagnetic interference (EMI) noise. However, the calculated spectrum of a noise signal by using a general FFT algorithm is different from the measured result obtained by using an EMI receiver. Because the intermediate frequency (IF) filter in the EMI receiver has a band-pass effect when filtering the signal, the measured...
A fully integrated 35GHz linearly Frequency Modulated Continuous Wave (FMCW) single-chip radar transceiver is successfully implemented in 65nm standard CMOS process. The single-chip transceiver is configured in one transmitter and two receivers and includes a wideband process-oriented optimized QVCO, a mm-Wave power amplifier, low noise amplifiers, low noise passive mixers, IF amplifiers as well as...
