Low Noise Amplifier (LNA) is one of the essential components in Ultra Wideband (UWB) devices. Conventional LNA suffers from large chip area, high power consumption and inadequate Noise Figure (NF). A compact UWB LNA in the bandwidth of 3.1 to 10.6 GHz is proposed. The design is based on inductor-less configuration using the resistive shunt feedback topology and noise canceling techniques for wi...

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...

In this paper, reduced power consumption, low-noise CMOS amplifier using chopper technique is designed, chopper-equalized amplifier had been used as a front end of a voltage-to-frequency converter instrument which performs pretty well, and they were meeting just about every specification, but they had a problem with undesired and unpleasant little offset shifts and jumps. Trying to solve this p...

This paper presents measured results of manmade noise impact on an cryogenic receiver front-end (CRFE) in urban and suburban areas in the 2-GHz band with amplitude probability distribution (APD). The CRFE comprises a high-temperature superconducting filter, cryogenically-cooled low-noise amplifier, and highly-reliable cryostat. The CRFE is expected to be an effective and practical approach to a...

This paper introduces wideband low noise amplifier design for Long Term Evolution systems. The three-stage, cascade wideband low noise amplifier structure will be presented. The low noise amplifier (LNA) is design for uplink channels for LTE systems. The LNA is designed for LTE receiver front-end which operates in 700-1300 MHz frequency range, covering almost entire LTE uplink frequency band. W...

In this paper a three stage Active Inductor (AI) based Low Noise Amplifier (LNA) for Ultra Wide Band (UWB) receiver is presented. A fully differential topology has been adopted in order to improve the circuit robustness against unwanted common mode signals. T-coil peaking is used to enhance the bandwidth over the entire Ultra Wide Band frequency range. Active inductor is employed because of its...

λ2 OC-192 We are manufacturing widely tunable laser diodes based on an integrated single chip design. The sampled-grating distributed Bragg reflector (SG-DBR) laser is monolithically integrated with a semiconductor optical amplifier (SOA). The continuous wave (cw) output power of the fully packaged device is more than 20mW over the entire C-band with low noise figures and a high side-mode suppr...

this paper proposes a low voltage (±0.55v supply voltage) low power (44.65µw) high common mode rejection ratio (cmrr) differential amplifier (d.a.) with rail to rail input common mode range (icmr), constant transconductance (gm) and enhanced frequency performance. its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...
