A drive amplifier consisting of a cascode amplifier and a local feedback amplifier is proposed to ensure high linearity. The local feedback amplifier with a post distortion technique compensates for the nonlinearity of a common-source stage while maintaining input impedance matching and a reasonable power gain. In addition, a process, supply voltage, and temperature (PVT)-compensated current mirror...
In this paper, design of low power high gain and high linear CMOS low noise amplifier (LNA) is presented. This LNA is designed using UMC 0.18-um technology based on cascode topology adopted with gain boosting Technique. To improve linearity feed forward cancellation (FDC) technique is used. This LNA is designed for 2.4GHz ISM band applications. It is consuming 2.6mW power from 1V power supply by giving...
This paper presents a design of a low power single ended CMOS LNA for reconfigurable applications including GPS, GSM (DCS1800, PCS1900), 3G (UMTS), WLAN b/g and LTE. Based on a wideband input matching, the LNA stages cover all band of interest while achieving a good trade-off between high gain, low noise figure and low power consumption. For multi-standard aim, the LNA selects the desired bands using...
A 40 GHz power amplifier (PA) driver for the remote antenna unit (RAU) transceiver of a mm-wave radio-over-fiber (RoF) system is presented in this paper. Mm-wave RoF is proposed as a complementary technology to fiber-to-the-home to minimize costs and to increase bandwidth. In order for RoF to be feasible, the cost of the RAU must be minimized through low-cost technology such as CMOS. The PA driver...
A 0.1–1.2 GHz power amplifier using 0.18-µm CMOS technology is presented with a small chip area. With 3.3V supply, the measurement results in this band indicated that the gain is better than 20 dB, the S11 and S22 is less than − 18 dB and −10 dB, respectively. The saturated output power is 20.5 dBm and 19.5 dBm at 433 MHz and 900 MHz with the corresponding PAE of 27% and 19.5%, respectively. The chip...
In this paper, a cascode low noise amplifier (LNA) with shunt impedance feedback topology for applications in ultra-wideband (UWB) systems is presented. The design was based on the TSMC 0.18 mum mixed signal/RF processes. Measurement and simulation results are approximate. Maximum power gain of 10.01 dB with a 3-dB bandwidth ranging from 2 GHz to 10 GHz, input reflection coefficient less than -10...
