A digital RF receiver front-end employing a DT filter is proposed for application to m-WiMAX & The SAW-less receiver architecture, where the large out-of-band interferer can be rejected selectively by using a scalable frequency response property of FIR filter. In addition to the flexibility of the DT filter, the new non-decimation finite impulse response (NDF) filter can be cascaded to a conven...

A fully integrated CMOS wideband Low Noise Amplifier (LNA) operating over 2.3–7 GHz is designed and fabricated using a 0.18 μm CMOS process. The proposed structure is a common sourcecommon source (CS-CS) cascode amplifier with a coupling capacitor. It realizes both low voltage drop at load resistor (Rload) and high gain over 2.3–7 GHz with simultaneous noise and input matching and low power con...

This work gives a design perspective on low-power and wideband RF-to-Baseband current-reuse receivers (CRR). The proposed CRR architecture shares single supply biasing current among both LNTA baseband circuits to reduce power consumption. discusses topology selection suitable procedure of the low noise transconductance amplifier (LNTA), down-conversion passive-mixer, active-inductor (AI) TIA ci...

A receiver's intermodulation (IM) spurious response attenuation is a measure of the receiver's ability to receive a modulated-input RF signal frequency on its assigned channel frequency in the presence of two interfering continuous wave (CW) tones. The receiver's protection against spurious response interference is a measure of the its ability to discriminate between the input signal at the ass...

This work presents a 2.4 GHz low noise amplifier (LNA) for wireless sensor network in CMOS 0.13-μm Silterra process. The forward body bias technique with cascode configuration has been adopted in order to implement a suitable LNA for low power consumption target. The supply voltage was varied from 0.4 V to 0.6 V as to optimize the tradeoffs for LNA performances. The simulation results show that...

This paper presents a low voltage wideband downconversion mixer using current-mode approach for multi-standard receivers. The proposed mixer uses a current mirror amplifier with an embedded passive switching core to achieve mixing function, which can combine the advantages of active and passive mixers simultaneously. The mixer is implemented using a 0.18μm CMOS technology and covers frequency b...

This paper presents a ultra wideband low noise amplifier for 6GHz Applications. This proposed LNA is the extension of inductively common source amplifier and in this design we used transistor multifingering techniques in order to reduce noise and improves gain. This LNA is simulated by using UMC .18um CMOS mixed signal/RF process in cadence virtuoso. In this design, used current source biasing,...

The demand for lower cost and form factor and increased re-configurability in wireless systems has driven the investigation of blocker-tolerant softwaredefined radios [1-4]. While promising, a reduction in system form-factor will result in lower isolation among antennas due to the co-existence of multiple ratios or lower isolation within duplexers for FDD systems due to their reduced size and/o...

This paper presents a CMOS RF receiver frontend suitable for ultra-low-power operation. In order to achieve desired gain and linearity of receiver front-end at a 1V supply voltage, current reuse and optimum gate biasing techniques are employed. The proposed architecture includes merged LNA and mixer, operating in the sub-threshold region, and designed for the 902-928MHz ISM band. The proposed c...
