“…Passive mixers can transfer low-frequency impedance at their outputs to their RF inputs ( [43], [44], [45], [46], [47]), and can thus be employed to provide a narrow-band response at RF. In [44], a resistor R followed by a passive switching I-Q mixer with 25% duty cycle LO, which is loaded by capacitors C, is used to achieve a frequency transferred impedance of a low-pass RC filter, centered around the LO frequency, at the input of the mixer.…”

Front-end linearity plays a crucial role in determining the overall performance of a radio receiver. Nonlinearity can impact performance in several ways, including degradation in sensitivity, reduction in gain and the appearance of spurious energy within the frequency band of interest from out-of-band sources. In this paper, an overview of techniques for enhancing front-end linearity is presented. Circuit and devicelevel techniques, as well as architectures for linearization are described.

“…In addition, the primary goal of integrated receiver front-end is invariably providing low noise and high linearity in wideband. To obtain such performances, the topology of the FTI using passive mixer is widely used [1,2]. Because it provides RF impedance translated from baseband according to LO frequency tuning, out-of-band blockers could be attenuated by the resultant high-Q RF filtering and a few types of such FTI-first receiver have been presented [3,4].…”

Abstract-A 41dB gain control range 6 th -order bandpass receiver front-end (RFE) using CMOS switched frequency translated impedance (FTI) is presented in a 40 nm CMOS technology. The RFE consists of a frequency tunable RF band-pass filter (BPF), IQ gm cells, and IQ TIAs. The RF BPF has wide gain control range preserving constant filter Q and pass band flatness due to proposed pre-distortion scheme. Also, the RF filter using CMOS switches in FTI blocks shows low clock leakage to signal nodes, and results in low common mode noise and stable operation. The baseband IQ signals are generated by combining baseband Gm cells which receives 8-phase signal outputs down-converted at last stage of FTIs in the RF BPF. The measured results of the RFE show 36.4 dB gain and 6.3 dB NF at maximum gain mode. The pass-band IIP3 and out-band IIP3@20 MHz offset are -10 dBm and +12.6 dBm at maximum gain mode, and +14 dBm and +20.5 dBm at minimum gain mode, respectively. With a 1.2 V power supply, the current consumption of the overall RFE is 40 mA at 500 MHz carrier frequency.
